Frostwire is based upon Limewire and shares much of its code. It's possible that the two programs might be in conflict. (Even if you're not actually using Limewire, the two programs might have made conflicting registry entries).
Uninstall Frostwire (or, possibly better, use System Restore to take your laptop back to a time before you installed Frostwire).
