merge replication agent error

Hello,
i have problem with merge replication agent. the agent stops with error message
"Der Prozess konnte die ?nderungen auf 'Subscriber' nicht aufz?hlen."
"The process could not enumerate changes at the 'Subscriber'."
Repl Agent Status: 2
Percent Complete: 0
Category:NULL
Source: Mergereplikationsprovider
Number: -2147200999
Has anyone an idea, what's the reason for this?
the merge replication process has been setup successfully in this database szenario and worked without errors. after adding a additional table to the replication schema and new setup of merge replication, the described error occurs.
Thank you for Your comments,
regards

Rene,
this is a generic , high-level error message simply indicating that the
merge agent ran into a problem moving changes from the subscriber to the
publisher. It can be caused by several different problems, and is not
necessarily a bug.
To get more info, you could enable logging on the merge agent (-output
c:\somefile.log -outputverboselevel 3) - see
http://support.microsoft.com/?id=312292.
Alternatively, most of these merge errors are solved by simply restarting
the merge agent.
HTH,
