Hi,
You can try shutting down the EMS, deleting the file "pushPullSetup.xml", starting the EMS, and repeating your tests.
If shutting down the EMS is not possible, you can also try the "removeConfig" command thru Telnet. Full details about this command can be found in the EMS API Definition document:
http://www.evostream.com/evo_evals/API%20Definition.pdf
For example, the following command removes config ID #11 from the configuration file.
removeConfig id=11 permanently=1
Note that the config ID is NOT the same as the stream ID. Use the "listConfig" to find the config ID of a particular stream.
Cheers,
Don
