Hi and Welcome to the Community!
Here is a KB that discusses that error:
Unfortunately, it contains nothing useful! Hence, I suggest this thread:
It starts with a process for cleanly starting over, and there is some discussion, and there is also a post (15) with links to older Desktop Software versions, if those are needed. Note that this is not, by any means, guaranteed to work...but it has worked for many to resolve issues they are having.
Good luck and let us know!
