An error has occurred during report processing. (rsProcessingAborted) The report server installa

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.|||

hi, this probleb caused becaus mainly of the initializtion of reporting services you need to initialize the reporting service in the sql server for that u need to do

start-->all programs>sql server2005-->reporting services-->configure>initialize -->check the box and press initialize button
