Trouble downloading from LabView

[MikePres]

We just now started to check our software and hardware (yeah, we're doomed, i know). After 5 hours of thinking what's wrong (3 times it was because we didn't put plugs in sockets ><) we thought that we done it and our first engine is about to go... so we started to download one of the built-in programs in to the... i don't know, cRio probably (i'm not the programmer in my team), and this suddenly happend!:

I'm home now so I'll be glad if someone here can explain what could have happend and what can we do about it... so I'll be able to pass the info to our main programmer or captain tomorrow.
We have no idea what's wrong and it's pretty late now so we can't call anyone now and we're away of our systems (they're in our school).
If I did something wrong with the asking of this question - please let me know so I won't do it next time.
thanks

What does your program ErrorDisplay.vi look like? the program seems to hate the file...
can you show us?

[MikePres]

As i mentioned, I'm not a programmer and we're not near our robot systems...
I'll tell my friend to check out this file... what should he be looking for in it? what can be the problem?
I'll update with the progress tomorrow but first we need to know what can we do about this... so you said first check our ErrorDisplay.vi?
then what?

[MiniNerd24]

Well it failed to download the FPGA labview library file so it could be a problem inside the ErrorDisplay vi or it could be in the actual FPGA labview library file. and to be on the safe side check to make sure it's in the proper folder before messing with the programs too much it could just have a misguided path.

ok, thanks I'll update tomorrow on how it goes^^

We're having the exact same problem. Program gets stuck on the same file ErrorDisplay.vi. This is one of the files that came with the labview distribution so not anything we wrote. Sometimes if I disconnect the cable, turn off robot, reconnect cable, re-run the imaging tool, etc. it works... but sometimes it doesn't. It has happened on more than one laptop (but it seems to happen more frequently on mine than on the others). If anyone finds out the reason for this error we would appreciate if you let us know (drkiraco at purdue dot edu)

Same problem for us as well.

"Failed to download NI_FPGA_Interface.lvlib:ErrorDisplay.vi"

I was able to browse my harddrive and find this file at:

c:\Program Files\National Instruments\LabVIEW 8.5\vi.lib\Robotics Library\NIFPGAInterface\Error Management\...

Upon inspection, I see nothing out of the ordinary about it to explain why it won't deploy.

Today we tried again and everything worked suddenly, we didn't change anything. this thing is very strange ><. BTW: we turned our motors and compresor for the first time today, yay^^.
Keep updating if something new happens

I'm at a loss for why that particular VI is causing the error. Have you updated your LV to the latest, update 2? It may also be useful to locate the VI on disk, open it, and see if it needs to be saved. It shouldn't need to be saved, but it won't hurt if you do. Please let me know if save was needed, and if this seems to help.

I suspect that this may be related to switching from one computer to another. As long as we keep using one computer, it seems to work fine. But then if we switch to another computer, sometimes we get the error. Once we manage to get that new computer to work (by turning off the robot, re-running imaging tool, and just generally randomly messing with stuff until something works) it keeps working and the error doesn't re-occur on that computer, until the next time we switch to another computer. not sure if that's helpful or if anyone else has noticed it.
