Unless there's a bug in mcomm where it transfers the wrong file contents (unlikely), I think it's likely your RAM filesystem is corrupted. Renaming won't help.
It might be correctable, but if you have the data elsewhere I would just cold start. You mentioned activating and deactivating DOS. You really shouldn't have to. Unless you're using DVI it's perfectly safe. More likely you loaded a corrupted file Maybe LNKFIL needs to be called? Actually, you could try that and see if it corrects the dysfunction.
