The problem is loading mods that have a Pictures\Game\Dialogs folder but no StartMenu.bmp folder inside. To load them, you need to copy the stock one into the mod's folder. This has nothing to do specifically with the mod launcher, however. You can launch mods from the mod launcher or by editing path.txt after you copy the file over.

Loading old savegames seems to result in a data file error. You can still load them from within the game no problem, however. New savegames created in 1.95 can be loaded from the mod launcher just fine.
