Mendix 3.0 Upgrade

I am in the process of upgrading my application to 3.0. When I try and run it, I get the following error when trying to start up: com.mendix.m2ee.api.AdminException: Initializing the ConnectionBus failed. at com.mendix.core.MxRuntime.C(SourceFile:427) Caused by: f: Could not retrieve version information from system tables at bn.a(SourceFile:148) at bn.a(SourceFile:98) at bm.b(SourceFile:100) at bf.a(SourceFile:38) at a.a(SourceFile:152) at a.a(SourceFile:129) at com.mendix.core.MxRuntime.C(SourceFile:422) at com.mendix.core.MxRuntime.a(SourceFile:197) at com.mendix.core.MxRuntime.b(SourceFile:156) at fz.execute(SourceFile:52) at com.mendix.m2ee.server.handler.HttpAdminHandler.handle( at org.eclipse.jetty.server.handler.HandlerWrapper.handle( at org.eclipse.jetty.server.Server.handle( at org.eclipse.jetty.server.HttpConnection.handleRequest( at org.eclipse.jetty.server.HttpConnection$RequestHandler.headerComplete( at org.eclipse.jetty.http.HttpParser.parseNext( at org.eclipse.jetty.http.HttpParser.parseAvailable( at org.eclipse.jetty.server.HttpConnection.handle( at at org.eclipse.jetty.util.thread.QueuedThreadPool$ at Any ideas?
