so i read all about it on other threads and forums yet nothing works,i tried all options available,last one was after installing rtw and patching it to 1.3 i installed barbarian invasion and tried patching it to 1.6...wont work,window pops out saying it will upgrade only 1.3 - 1.5 versions of rtw,and that makes no sense since i patched it to 1.3..i m losing my mind here so any help is welcomed..thanx.
