Could not start TeamCity server with current settings.

Hi, 

this is on a TC 7.0.4 on windows 2k8 R2 an instance we are decommissioning.

From looking at the teamcity-server.log, it looks like the service was restarted and we started getting the error below:

Server startup exception: jetbrains.buildServer.rootDispatcher.UnknownStartupError: Could not start TeamCity server with current settings. Check that database and data directory are correctly configured.
jetbrains.buildServer.rootDispatcher.UnknownStartupError: Could not start TeamCity server with current settings. Check that database and data directory are correctly configured.

at jetbrains.buildServer.rootDispatcher.TeamCityDispatcherServlet$1.run(TeamCityDispatcherServlet.java)
at java.lang.Thread.run(Unknown Source)

This instance is using HSQL, other than checking the buildserver.data files is in the expected location I am not sure what else to do. Any advise willingly accepted :)

Thanks
