CREO won't launch anymore

Hello everybody,

After a lot of searching on the web I have no remain options other then asking. So I've used PTC Creo 3.0 for now 2 years on my desktop computer for my studies and suddenly one day PTC CREO refused to launch and since that day it doesn't want to start anymore. When I try it shows me the loading pointer that disappears after few seconds and that's all. I've tried the following solutions :

- Uninstall/Install on different disks, in administrator.

- Clear Cache and appdata files from PTC.

- Verified my drivers.

Thank you in advance for helping and have a nice day!
