Fences keeps disabling its self

Hello,

I've just reinstalled Windows 8 and got it fully up to date, only installed fences and avast so far, fences worked at first and is fully registered but now it keeps closing / disabling its self moaning that there is something wrong with explorer.exe but i can't see any evidence of crashing from Windows etc.

I've uninstalled, restarted, installed again and still the same problem.

Really annoying, love this product but it appears to be so buggy.

Many thanks in advance
