Hi Mark,

I checked windows log and firebird.log.
There is nothing there. The server seems fine.
I'm running superserver.
First I thought that it is a network problem but then I noticed the problems happens on localhost

The stackstrace does not say any more than the message.

See com.borland.dx.dataset.DataSetException error code: BASE+66
