If you patch with patch 2 and then temple.zip (which includes the level uncapper) instead of patch 2 and just the uncapper, then you should not have this problem. It's one of the many things moebius (author of temple.zip) fixed.
After unzipping the fix, replace the file in the game folder called "temple.dll" with the new file of that name from the .zip, then transfer the three folders from the "data" folder in the .zip to the "data" folder in the game. After that, you're all set, and m.m. should work great. Does fer me.
