As mentioned, please post more info, but my guess is that in Begin, some form of I/O based on the FPGA is no longer opening due to the latest modification. Without more of the error chain, it can't be narrowed down. I'm not really sure why the error is first showing up in the prep dashboard code except that it reads virtually everything in it's current form. If this is how the tea leaves dry out, focus on fixing the open error and all should work fine.
