I keep getting an error when I try to save my documentation session, it says it cannot write to the file (TDP_Document). Because of that, I can't save an check in my project so I lose all of my edits. Sometimes it will say it can't write the file because it is in use by another process. Today, I tried to remove the TDP_Document and it said it was in use by Micosoft Excel. When I quit MS Excel, I was able to remove the file. It seems there is a conflict between Valor Process Prep software and Excel. I believe the reason it can't write the TDP_Document file is because it thinks MS Excel has control of that file.
