How to use RSA7.5 to connect RTC2.0

Hi,

I am trying to use RSA 7.5 as RTC clent. The version of RTC server is 2.0. When I tried connecting to RTC1.0, it worked fine. But when I am trying to connect to RTC2.0, I am some error and its not connecting. The error message is below

"Client/server version mismatch logging into 'm/c name'.
CRJAZ1176I There is a version mismatch for the "com.ibm.team.repository.common.internal.IRepositoryRemoteService" service. The server version is "7" while the client version is "6". Both client and server version must match. Check the overall version of the client using Help->About and ensure it is compatible with server version "1.0" and build id "I20090618-1753".".

I updated my RSA7.5 to 7.5.3. Even then I am getting the same error. Has anyone tried to connect RSA 7.5 to RTC2.0?

Thanks
