I had TM on an older system and it had no problems with the mods I installed at the time. Could not find install for the old version. I just bought TM again and installed on my computer. Played a few rounds and then installed the Master Flags, Weapons and tank packs. Now when I play, I get a lot of repeating sounds. (Ex., flower power repeating through the game. Trumpet repeating. Etc.,.) Some sounds disappear, such as "You Win" or announcing which tank won. I am running Vista 64.
