Unable To Perform "Save As" to TIFF from Raster Manager

I am attempting to perform "Save As" from Raster Manager with an orthomosaic file that is attached to my drawing. When I attempt to perform the "Save As" I see an error at the bottom of the screen. The saved messages read:

X:\GIS_Orthos\3711A\MOSAICS\3711A.tif
Foundation class exception - [2]
Error generating output file: X:\GIS_Orthos\3711A\MOSAICS\3711A.tif
Foundation class exception - [2]

It generates the TFW file but bails when writing the TIFF file. This is not a permissions related issue or a bad path. I do this every day and it has worked fine. Tried the standard fixes, reboot PC, etc. No luck. Any ideas?

Platform is Win7, MSV8i (SELECTseries 3) Version 08.11.09.459
