Visual Studio 2008 Crashes after installing WSP builder

We had an issue today where Visual Studio 2008 on Windows Server 2008 SP2 was crashing. This started happening after we installed WSP Builder 1.06. We had the following Event in the Event Viewer (Event ID 1000).

Faulting application devenv.exe, version 9.0.21022.8, faulting module 47317b3d, version msenv.dll, fault address 0×9.0.21022.8.

The problem was fixed by uninstalling WSP builder, Installing SP1 for Visual 2008 and Reinstalling WSP builder 1.06.

WSP Builder works like a charm now!
