Won't let me start new year - Sage 2014.3 - Database error - Historical data problem

SUGGESTED

Hello,

I have been using Sage 2014.3 since well, 2014. Have had the odd issue here and there but never did. Tried to start a new fiscal year, was told it can't go forward because of a database error. I did the advanced database verification and was told an error was found but that it couldn't fix it.

I opened the log and found this :

Unable to convert MySQL date/time value to System.DateTime

I will preface by saying that my datafiles are located on a Dropbox, which after doing some reading on this forum, is not the best idea. I have been doing that since 2014 and have never had an issue until now. That being said, I will not do this going forward, but still need to figure out how to repair my data file.

Anything I can do? I have tried opening a few older backups, to no avail. Not sure how far back I would have to go - can't imagine having to redo the whole year...

Thank you!
