InfoPath Dev

I recently tried the Office beta 2010 to check out new features in infopath. After trying to rollback I am now unable to get my infopath project to open visual studio tools for applications through the programming menu option. The error I get is unable to load context. Does anybody know what I might have broken?

I reinstalled Office 2007 Enterprise and VSTA and now everything is work again. I was hoping to see some new features in Infopath 2010 that I needed, unforntunately the printing support is still subpar imo. I did like the feature that allows you to send your print view directly to .pdf from within Infopath, that was pretty cool.
