Hi Larry,
yes I had tried changing Options - > 2. Audio -> Audio Temp Directory (defaults to C:\Users\"whoever"\AppData\Local\Temp\). I changed this to C:\bb\Temp but that didn't seem to help. I saw some files in the original temp directory but didn't research it much after seeing that changing it to C:\bb\Temp didn't make any difference. Realband.exe had full access running as Admin at the time.

After the re-install, I'm running Realband and Biab as a normal user which is how I had always run these programs in the past. (Been using the software since 2008) I've tested the heck out of both programs by creating new files in Biab, saving them and opening them in Realband then saving them multiple times as .seq files with no problem. Even the old .seq files that were especially troublesome are ok now.

It certainly seemed like a permission issue but a re-install cleared it all up for me.

The only problem I'm seeing now is there appear to be some realtracks and realdrums missing from my re-install. (I may have not run everything in the right order.) I plan to call tech support on Monday and see if they can assist me with getting back those tracks. I think they were in a bonus pack I had bought a few years ago and I may not have the original .exe file for that. They should have a record of what I bought anyway and can tell me if I should have them or not.
