I get the following error when loading a project file.

Possible Version mismatch. Type System.Collections.Comparer has 1 members, number of members deserialized is 0.

It references mscorlib as the source of the error.

The machine I am having trouble with is running Windows XP 64 and has both Visual Studio 2003 and 2005 installed. I have a second machine running Windows XP with both VS2003 and 2005 installed and it runs fine.

I have verified that the versions of LLBL are the same.

Any ideas?

Mike

It sounds more like a .Net framework mismatch. The lgp file was created using version X of the .Net framework and now you are trying to open it using a newer or older version.

Does the machine with a problem has .Net 1.1 Service Pack 1 installed on it? If not, try installing the SP.
