No specific crash of wd220vm.dll (no replies)

Hi,

I have a program that is using a Dot Net Assembly. Everything is working well with the exception that I'm getting periodic application crashes of referencing wd220vm.dll. It doesn't seem there is anything wrong with the code and 90% of time it works fine but the rest of the time I get a crash with following error. Any ideas?
