XML error

have a pdf form i was using and edited it and saved it;closed it; opened it; edited it;saved it.   Next day i went to open it, and get XML error and then file opens with these words on what looks like a blank document "the full content of this file cannot be displayed with your current PDF viewer. please update to the latest possible version to view this document"

tried the chat help at adobe and they had me try to open with google chrome - to same result.  Then i asked if i can submit teh file to adobe for someone at adobe to look at, and chat person told me i need to do that/ask that via Adobe Support Community.   Question:  Can i submit this file somehow for someone to look at to try to open, or to extract the data?
