Mysql Datasource Issue Follow

Hello Damian,

The problem is not in drivers or anything else except that IDEA for some unclear reason
cannot communicate with a helper process hosting an RMI registry.
This process is used for all mysql-related activities.
Please ensure with the help of your favorite process/TCP manager that a java process is started
by IDEA and listens/reachable on specific port for RMI requests on any mysql-related request from the IDE.

HTH,
Gregory Shrago

The settings are correct, as the datastore previously functioned perfectly and the underlying database has not changed. I can't pinpoint exactly when it stopped (i.e was it when i updated idea, etc ??? no idea)
I've also tried removing and readding the datastore, which fails when trying to test the connection.

I'm running the following
idea 9.0.3
mysql 5.1
mysql connector 5.1.12 (have also tried version 5.0.8 and 5.0.4)
windows 7 64bit with ip v6 enabled

I've tried disabiling the windows firewall, playing with network settings, etc but to no evail.... mysql is definitely listening locally on port 3306 and i've tried connecting to localhost, the pc's actual ip and 127.0.0.1 address...

Any ideas would be appreciated as this is becoming frustrating.
