Support center stopped working

Hello there,

Lately support center doesn't want to work, after some seconds a "the application stopped working. windows is looking for a possible solution" message pops up. needless to say, windows never found a solution. I tried uninstalling and doing a clean install of all the dell support suite several times with no luck, i don't have any antivirus on, except windows defender. 

I'm trying to run SC version 1.0.665.2 on win 8.1,

I wanted to run a scan because after installing win 10 trial version and going back to win 8.1 my workstation is acting pretty weird (and sloppy).

Hope someone out there can help!
