I'm sorry to be writing this in English here but I'm not able to write in German
I appears that that website endpage.market-cube.com
is having some issues which interrupt the payments for some of you.
I suspect this is caused by the anti-virus that you may be using, but I need confirmation from you.
I've suggested, to those that submitted an helpdesk ticket, that you should disable it before attempting this survey again.
Did any of you tried this survey again after disabling the anti-virus, and did it work?
