Hi Libor,
I can run TDP manually from the task scheduler just fine. In fact, when this prompt comes up about it having to close because of the error, I usually hit OK, then manually run that task through task scheduler again and it runs fine.
Regarding your suggestion, I did rename that file and then reran a task and let it recreate a new folder as of today. It successfully did this, so hopefully that may work. I'll keep my fingers crossed :)
I'll watch this throughout the next few days and see how it goes and will report the findings.
Thanks!
Chad
