Yes, sorry, I should write here more often. All works now, it was a problem on my side afterall. Not from Supermedium.
Your offer was overwelming, but I could and won't take it. Nevertheless, thank you for consider it. Was really unexpected.
Your help and the work you put in this project is awesome.
Again, thank you. You are making the best out of it, and I am sure that the project will succeed.
Regards,
Rene
