Student Archicad26 on Mac - 'Serial number validation failed'


Hey guys, 

I have a student version of Archicad 26 on my Mac and when I try to activate it, it gives me an error saying "Serial Number validation failed”. Serial number, username etc are all correct. I've already tried restarting my computer, deleting all Archicad verisons and reinstalling them, trying Archicad 25 etc... Does anyone have any suggestion how to fix the problem? The first screenshot included shows the correctly entered info and the second one shows the error immediately after clicking restart Archicad.

Thanks in advance!
