Can't reload x4 Please help

Please help!!  I tried to reset my setting back to default using the F8 key and for some reason after doing that Corel would not open, it went to the start screen then froze up.  So I figured I would just uninstall it and re-install and that would fix the problem.  To my surprise when I went to re-install this is what I got, The Terms box is blank and the only option is to close.  I thought maybe it was the cd, but it will load on my laptop, but not my desk top.  I then tried to download a trail version of x7 and the same thing happens.  This has been going on for 2 months, I've tried all the suggestions I could find on the internet and nothing is working, can someone please help..  I ran this on the same computer for 2yrs without an issue- Windows 7 with intel i3
