Im using gametap to play worms armageddon but the thing about it is I can't figure out how to install custom maps. Apparently the game is running through the program and I don't see worms armageddon on my harddrive. Is there anyway I can install the maps?

If gametap is installed, won't that have its own folder on your hard drive somewhere? Try poking around inside that and look for a Worms Armageddon directory.

If you still can't find it do a system-wide search for something like "BankEditor.exe" - that file is in your User folder where all the customisation stuff goes.

Gametap, huh? Another downloadable games service.
I wonder what version that game comes in or if it is patchable.
