Windows 8: MCE remote completely stops working

unsure if this is a windows 8 problem or to do with XBMC

But it all works fine then after about 5 mins the remote just completely stops working till i restart.

this happens everytime, its quite annoying as you can imagine, and happens on 2 of my HTPC's.
Both use RC6 remotes,

one has Xbmccustomregis v2.60.12

and the other is just out of the box settings.


any ideas?



If ive posted in the wrong place sorry lol
