All of a sudden, after having no issues for months, QB2013 started with this error on boot.

Tried the delete on the 'entitlement' that works for that boot, but comes back on next.

Tried the QB Install Repair. That works, again only until reboot.

I check all the files, they are all there. SOmething has gotten messed up.

I have NEVER understood WHY this program has SO many problems. I have had to re-install at least 5 times
