Beats me. If this is an isolated incident I'd just forget about it and move on. You seem to be pretty active here so one screw up isn't going to make a big dent in your rating in the long run.
BUT if this is not an isolated incident or you're really curious click on Help & Support and contact the staff. You can also go thru my blog below and see if any of the steps there help (such as clearing the cache for instance) if this glitch re-occurs.

Computer2-MEDIUM didn't make his Move for >10 min ( in our Blitz Game,10/10 ).. I waited till it ran down to 0 sec ,but then it says it won on time instead n' I lost 7 points ?
.. but after the game,I checked my Live Chess Archives Page n' it showed he made did make a move but it wasn't showing on my Board during our Game .

My Game as shown on my Live Chess Archives Page.
My Board didn't look like it did on my Live Chess Archives Page .. after the game ,it still showed my move as the last move but it reversed our time left instead .. that is I now had 0:00 time while he had 10:55 left.
( During the game,it was the other way round : I had 10:55 and his time ran down to 0:00 )
My Game after it ended ,on the Actual Live Chess Page .
Is this a Glitch or due to lag or ?
( I act thot he violated the Fair Play Policy by not making his move for >10 minutes ! .. lol )
Tnx .
