It sounds like something is definitely wrong with this particular machine (since it's working on your other computer). The odd thing is that mmMainMenu has always been a part of MM .NET...it's not a new class! It MAY be that your installation of VS .NET on this machine has been compromised. Before going through the drastic measure of uninstalling and reinstalling .NET, try this:

1. Uninstall MM .NET

2. Using Windows Explorer, navigate to the GAC (Windows\Assembly or WINNT\Assembly) and make sure there are no MM .NET assemblies in the GAC. If there are, remove them.

3. Using Windows Explorer, navigate to the directory you installed MM .NET into and make sure all directories and files have been removed, if not, delete them.

4. Do a search on the computer for a file named "Mere Mortals Framework Windows Forms.dll". If there are any instances, delete them.

5. In the MM .NET Developer's Guide, check out the topic "Installing the Mere Mortals .NET Framework 2003". At the bottom of this topic are a list of all registry entries. Make sure these have all been removed from the Windows Registry.

6. Reinstall MM .NET.
