Is that the full extent of the error message?
What were you trying to do when it happened?
sorry it all didn't copy over
"error opening archive.Internal error, archive, 00005BB0, DOC Control does not exist"
I am getting the same error message but trying to access an older PDF file. I have done some digging and think I have found a solution. the "000055bb0" is a location of the actual file located in the EPDM_Data directory...for at least to me, it represents the directory where the location where the file was...this is just a hunch..but I am going to go back over some older backups to see if that would be the case.
I had resolved my issue that I was having. it may apply to your issue as well.. Under the EPDM_Data folder, look for the directory of the last digit of the error..in your case 0 (look in the folder named '0') search for the 00005BB0 folder, open it, copy what's listed there (to you desktop) go back to where you were trying to access the file. delete and drop in the one you just copied..then try to open it back up. Its what I did for PDF files...I hope it helps.
