Trading Network Error

Hi,
When I start TN, it says,
There was a database error fetching the model version information from your database.
(0) COM.jbms._6._3130: Failed to start database ‘TradingNetworks’, see the next exception for details.
(1) COM.jbms._6._3130: Failed to start database ‘TradingNetworks’, see the next exception for details.
(2) COM.jbms._6._3130: Cannot redo operation null in the log.

class:com.wm.app.tn.db.DatastoreException

It was working fine a day before. I just restarted the server and after that, it givimg me this error. I am using WM 4.6 and using internal db.

Thanks
NN

ok, its working now. I just unzipped tradingNetworks.zip from the packages–>wmTN in the data directory into the trading networks directory. Then restarted server and all things back

Thank You
NN
