Tixati was working fine for over 6 months now. But yesterday when I was opened Tixati, it did not respond.
So I tried different things to fix the problem. Finally I went to '%appdata%\tixati' folder and deleted the scheduler config files and I was able to open Tixati again.

After that when I defined a new schedule (to change bandwidth preset), Tixati does not respond and the UI hangs.

I'm using Windows 7 x64. I tried both Tixati 1.96 x86 and x64.

Please advise.
