I'v reinstalled RS, then I configuret it. But when I want to open a report raise this error

An error has occurred during report processing. (rsProcessingAborted)

The report server installation is not initialized. (rsReportServerNotActivated) (rsRPCError)

Any Ideas

Thanks in advanceIt happens because another instace of RS was running.
See it at:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/RSerrors/htm/Microsoft.ReportingServices.Diagnostics.Utilities.ErrorStrings.resources.Strings_rsReportServerNotActivated.asp
I try to do this to solve this stuff:

rsactivate -c "path to the report server config file"

rsactivate -r

With no luck.

Any Ideas?|||The error was cause I lose the encription key. Then I deleted with

rskeymgmt -d

After that I have to reconfigure all the connection.
