Link Not working

All of a sudden my BlackBerry link that has been working great, with my z10 and playbook, now it gives a message that it can't connect to either one, U have tried to repair it, and Un installed and re installed, same thing, is there any known problems that I'm missing or has this program became corrupt?

Posted from my Z10 on CB10

Plenty of known issues, very few solutions.

Roll back windows, install older versions, CCleaner... Use whatever you can to get RID of all BlackBerry software, clean up your PC and then try installing agian.

Best of luck! Link issues are the worst...
