Maintance plans corrupted with sp2...

I installed sp2 on my sql server2005. It failed on database engine service. And i am not able to open my maintance plans or create new plans.
When i try to open existing plan i am getting the following error:
Unable to cast COM object of type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.PackageNeutralClass' to interface type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSContainer90'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{8BDFE892-E9D8-4D23-9739-DA807BCDC2AC}' failed due to the following error: Interface not registered (Exception from HRESULT: 0x80040155). (Microsoft.SqlServer.ManagedDTS)


Any help appreciated...[:0][:0]

See if re-registering the DTS.DLL helps..

regsvr32 “Crogram FilesMicrosoft SQL Server90DTSBinnDTS.dll"
