Whenever I open HEM (as of ~24 hours ago), it tries to optimize reports for my screenname on each site. It won't allow me to import hands or look at any reports while I play, so it basically makes any in-game benefits useless.
I saw somebody had a similar issue (didn't want to hijack) about a week ago, so I followed some of the steps in that thread, but no luck yet.
So far, I have tried to update both the beta version and the 1.08.04 version and have the same issue on both.
I don't know how to do the next option you suggested (something like PGA>Maintenance> a few other things), but I'm going to try to backup the database now. I have no idea if I have lost hands or not yet.
