G2 Control panel error
 

I am running win XP with G2 version xx.xxx.570. Recently I tried to upgrade to the latest version. SOmething went wrong while updating and the server stopped midway. This has messed up the control panel in someway. When I try to upgarde the software now, it throws up the following error.

AppName: cpanel.tmp0 AppVer: 2.0.0.292 ModName: cpanel.tmp0
ModVer: 2.0.0.292 Offset: 0004c9ef

Is there a way to get a cpanel.exe file to repair this file? Moreover, is there a way to upgrade the software without going thru the pains of trying to connect to the already busy server.

Thanks,
Anurag
