Where the Gurus meet to share their Artlantis knowledge...
There is not much information to go on here. My suggestion is that you log an official Support Call on Abvent's website. In doing that, you will receive a Ticket Number which will enable you to track the problem right up until they find a solution for you.
Once you have an answer, it wold be great if you could post it here for the Members to view.
I'm having the exact same problem. If you would, post the solution to this problem as a reply for me. I would greatly appreciate it. Thanks
