I searched google and anandtech's forums before posting this... I came back to my parents' house to 'fix' their computers (usually just retweeking a few settings). They were having a hard time conneting to the internet, and through a trial-and-error approach, I diagnosed the router as the problem. With a new router came internet connectivity, which was good. The problem is that my father wants to install Iolo System Mechanic 7 Pro. Try as we might, I cannot get it to connect to their servers for cdkey verification. Furthermore, I can't seem to get the iolo download manager to work when trying to download a diff version of SM7Pro. Which port should I unlock to fix this? Or does anyone have any advice? We're currently using a Belkin G+ MIMO router. Any help is appreciated!
