All comes to an end ...
Because of the insolvency of WUG all operations regarding X-Setup Pro have been shut down.
We thank all customers, partner and friends for their support during this time. We hope you had as much fun using X-Setup Pro as we had making it.
We wish you all the best,
TeX and Eric
