Hi Vladimir Byrne,
I believe the problem is coming from the version you are using. I have never experienced such an error, however after searching in the web for a little while I found some people with your problem and all of them said that they fixed the issue by installing another version of VS 2008 like this guy here
I am not really sure what is the problem with this version but I advice you to try and install this VS 2008 version : http://www.microsoft.com/downloads/details.aspx?FamilyId=FBEE1648-7106-44A7-9649-6D9F6D58056E&displaylang=en
Make sure that it is SP1.
Hope this is helpful.
