A few days ago I explained about a problem I had opening my QB on my office computer. I've use QB forever (since 1995) and I've run Win10 for over a year now. Suddenly, QB wouldn't open.

I rebooted. I Uninstalled & Reinstalled QB. Same error. I downloaded a QB troubleshooter program (by the QB folks). Still no solution. So, I gave up & ordered QB 2016. Loaded it this a.m. & it works great.  I just wasn't ready to upgrade yet, but now it's over. All my previous QB files opened just fine. Even my unpaid bills were still showing. All is fine, but I'm $185 poorer.
