need new log4net to match Crystal Update

I just installed the new update 12 for Crystal Reports. It includes all the CrystalDecision DLLs but does not include the log4net.

This new version has PublicKeyToken starting with 692fbea........ When I run my app now, it gives me a YSOD, complaining that it can't find the log4net with PublicKeyToken starting with 692fbea. I've got log4net in my web.config set with the old PublicKeyToken (starting 1b44e1d) but the YSOD still complains about not finding the new one.

Where can I get the new version of log4net with the new PublicKeyToken?

Thanks

Dave
