Can't get TC working with SQL Server? The JDBC Driver has been forcibly unregistered

Hi,

I'm trying to get TeamCity working with sql server and I can't seem to get anything going, here's the environment details:

- Win 2008 R2
- SQL 2008 R2 Express (Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64))
- Team City 7.0.2a
- jTDS 1.2.5

I've tried to follow the instructions here:http://confluence.jetbrains.net/display/TCD7/Setting+up+an+External+Database

Here is my database.properties file:

connectionUrl=jdbc:jtds:sqlserver://localhost:1433/TeamCity
connectionProperties.user=TeamCity
connectionProperties.password=*****

# The maximum number of connections TeamCity can open on database server.
maxConnections=50

# Specifies whether TeamCity should check each jdbc connection before use.
# It reduces the system performace but avoids cases when the system uses
# a connection that was closed by database server due to time out or this
# connection was broken at the previous operation.
testOnBorrow=true

I've also tried the naitve driver but still I receive the same errors.

Any idea how to fix this as I'm really stuck now and we don't want to use the inbuilt database for our production environment.

Thanks

Dan
