|How did you upload i.e.8rc1????|
Do you mean upgraded???
First thing is first....
Beta is a test program that shouldn't be used by just anyone....It is mainstreamed to allow all the IT and other computer professionals the use of the program for working out the bugs....There are no fixes for beta programs other than uninstalling and re-installing the source...
With that said it is apparent that the beta program has an issue with the upgrade. You need to either report the problem to microsoft or uninstall it and try again to upgrade or wait till the patch that will repair the issue to be designed and made available for download.
More than likely you should have removed the beta to install the other!
