What order did you install your NI software? The correct order is to install needed NI LabVIEW Modules before installing drivers. In your case, I want to ensure you installed LabVIEW, Real-time Module, and FPGA Module, then install NI-RIO 3.2.1. The file I/O errors could be caused by the compiler looking for driver files that are not installed because the RIO driver didn't detect the FPGA module was installed. If you think you may have installed out of this order, I would recommend repairing the NI-RIO installation.
Are the NI applications installed to their default locations? Perhaps the compiler is looking for a file in its default location but your applications are installed on D:?
The reason I pointed you to CompactRIO documentation is because from a software perspective, CompactRIO and Single-Board RIO are nearly identical, but the documentation for CompactRIO is more thorough. The main difference between CompactRIO and Single-Board RIO software is that Single-Board RIO does not currently support scan mode.
The last thing I can think of this morning, is to check the conditions of the FPGA client temp folder. I have seen issues (when compiles have been aborted, for example) when the temp folder is left in a state that the FPGA compiler can't successfully interact with it. Check the path:
C:\NIFPGA2009\clntTmp
and delete any files that appear there to give it a fresh start.
