Such behaviour is usually not the fault of any particular program which exhibits it, but of something else interfering or system instability. So do with it as you would in any such case:

- Do a full anti-virus check to make sure your system isn't infected with any malware;
- Disable your security and anti-virus programs temporarily to see if they're not blocking Tixati somehow;
- Do a full uninstall and reinstall Tixati (backup your .torrent files if needed!).

If your difficulty persists, please make sure to give us more detail so we can help you better, such as:

- What happens exactly when you try to run Tixati, are there any error messages produced, etc ?
- Are there other applications in your system giving you problems ?
- Anything else you think it's relevant.

Good luck!
