ASPNET error while accessing sql server report manager

[amitda]

I am getting following error while trying to access sql server report
manager:
I saw an msdn article about similar issue, made sure c:\temp exists and
pointed TMP and TEMP sys env var to that. Also made sure Temporary
ASP.NET Files directory can be accessed by NETWORK SERVICE and ASPNET
accounts.
Still no luck. Anyone can suggest anything else????

Please help.
Thanks
