Hi,

I can't seem to open a project file keep getting the error below. I am really stuck with this as it is stopping me carrying out any further work on the project. Any ideas.

.NET 1.1 no service pack one - it was installed but I removed it.

Message:

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

Stack Trace:

-----[Core exception]--------------------

Any ideas?

It appears that when you install SP1 it will be fixed. See this thread: http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=1466

Did you had SP1 installed previously, then worked on the project, saved it and now try to load it without SP1 on your machine?

Hey ! Otis posted 5 seconds before me.

Thanks for the quick replies.

Yes SP1 was installed, shall I reinstall it?

It's the only way you'll be able to load it again. An LLBLGen Pro project is serialized using the binary formatter to a file. If you use a different framework now which has a lower version number, the .net deserializer can't find the assembly required and gives up.

All working now.
