weird Bonus Packs problem

Hi,

I have unreal tournemant installed and downloaded 2 free mission packs, they are .umod files, i double click on them and am supposed to enter a folder name it points exactly where ut is located, i press next and the freakin stuff says ut needs to be installed in that dir !! what is wrong ???? ut is installed there and i can't figure out what's wrong, i had it installed b 4 but now it refuses to install, i have ut patch 4.13 also installed,

someone nows what's wrong, i'm doing wrong ?

path is correct , i checked a million times (well not that much) but i took path from explorer and pasted it into the installer also pressed reset wich also gave right path didn't work and i don't want to reinstall ut al those maps downloading again et

that wasn't my problem cause when i double click a umod file the installer pops up

yeah guess i'll have to do that don't fortget about the cache dir for the downloaded maps and i keep my user and unrealtournemant ini files too and see what it gives
