I did the same as you, got rid of pop ups, but the problem I have is that the captcha keeps failing, I tried it several times, my brother tried it, and it said it was wrong everytime, and then tried to make me download a jscript file that had some random name. after a while I ended up with the limited downloads reached message, when I hadn't even downloaded anything yet. what confuses me is that I had the supra mod he made before, I had my PC upgraded and now I cant get any of these mods.
I've had some many problems with that particular website in the past though (it's broken the PC im on right now twice after getting virus's from it, that's with a ant-virus aswell)
seems the only way i'l be able to get combat's great mods is if there are additional links to mediafire or MEGA (which atm are the only sites I trust)
