flirc unresponsive every day or two

[aluders]

I've had my flirc for around 3 years, never had a problem.  Recently I was getting false triggers from what I assume to be some new lights.  In the process of troubleshooting I installed the latest flirc version and it updated the firmware on my flirc from version 1 to 3.  I was able to fix the false triggers eventually by erasing the flirc and experimenting with remote commands that didnt get false triggered.  The firmware version did not help however and ever since the update my flirc becomes unresponsive every day or two and I have to unplug it and plug it back in.  I would love to just revert back to an earlier version (I know firmware 1.0 worked fine) but I cant find a way of doing that.  Any help?
