Crashing RDS

The RDS service crashes with the following error

 

Faulting application rds.exe, version 6.0.653.0, faulting module libob2ecmn.DLL, version 6.20.400.0, fault address 0x00034645.

 

I recently upgraded to 6.20 and i am not sure if something went wrong. Should the RDS have upgarded to 6.20 during the upgrade? it still shows the version as 6.0.653.0?

 

Any help would be appreciated.
