#4379 java.io.FileNotFoundException when any player joins

[Obvious]

MegaMek release 0.39.4, MegaMekLab release 0.1.33, MekHQ release 0.3.7.
Megamek launched from within MekHQ. Windows.

When any player joins (including non-bot), an 2 errors are logged. See bottom of attached log.
There doesn't appear to be anything obviously failing, though. Everything appears to still be working.

That was my fault. I forgot to consider that the MM.jar file doesn't exist in Windows and Mac releases.
