Visual Studio Express Startup Error -3xAVCore.dll

I you get this error on Win7-64 with the new Visual Studio 2010 :

Problem Event Name: BEX
Application Name: vcsexpress.exe
Fault Module Name: 3xAVCore.dll

then its the fault of MySpeed from Enounce
(a very handy tool with which you can watch Flash in variable speeds)
A quick workaround is to rename the dll, which will stop Myspeed from working but also fixes the Error.
