I bought a license of VS.PHP for VS2010 last week and have been noticing some problems. When I click on a solution file in Windows Explorer to open up VS2010, I will be prompted with a dialog saying the trial period has expired. I click through saying I'd like to activate my copy, enter my license details, and it seems to load just fine, but as it begins loading the files for the project, I get stuck in an infinite loop of error dialogs that mention "Object reference not set to an instance of an object." This doesn't crash VS2010, but it does make it unusable so that I must end the devenv process and restart.

None of this happens when I start VS2010 and open a solution from within VS.
