Updating from build 201 to 202 problem

 
When updating from build 201 to 202, everything works fine until the last step. When I click the button to re-start, MT4 re-starts but opens back with the update screen again as if the update never occured. Any ideas to fix this?
 
Download build 202 manually "MetaTrader 4 trading terminal"
and install it on existing terminal
