Trouble with deploying program

[sparks-1784]

Hi. We've been having some difficulty in deploying programs to the cRIO. We updated cRIO with the latest image and had deployed a program but it didn't appear 'take'. Subsequent attempts to program showed a communication timeout with the cRIO.
We then attempted to re-image the cRIO and had the following error:
Unable to complete operation because of unexpected error:
Error 56 occurred at TCP Open Connection in NI_InternetTK_FTP_VIs.lvlib:FTP Open Data Connection.vi->NI_InternetTK_FTP_VIs.lvlib:FTP Data Send.vi->NI_InternetTK_FTP_VIs.lvlib:FTP [STOR].vi->ConfigUtility.lvlib:2012_FTPSubFolder.vi:1->ConfigUtility.lvlib:2012_FTPFolder.vi->ConfigUtility.lvlib:ReImageTarget.vi->ConfigUtility.lvlibialog.vi

Possible reason(s):

LabVIEW: The network operation exceeded the user-specified or system time limit.

Not sure what the issue is here. One possible problem is that the framework we used to create our program may be compromised (just a guess). Instead of re-drawing the program from scratch, there is a strong 'desire' to copy bits of last years program for expedience sake. I noticed that when this was done, the compressor commented code in the periodic tasks vi was not in the code at all (commented or otherwise - and no, our compressor is not working because the control loop stuff is not in the periodic tasks vi).

Can anyone provide some hints here? Trying to load code into the cRIO has never been more difficult than this year and I have to think that we have a basic configuration problem.
