GA4 activation problems

hope you can help:
I unzipped GA4 successfully but the activation period in my eLicenser keeps showing errors:
‘Activation period cannot start please contact your vendor’. Drivers are updated and maintenance carried out. It shows on my elicense but when I press the ‘activation period’ button the error message shows. It does not show up in My Steinber could it be a problem at the Steinberg’ end?
After all the problems with GA 3 this is not an auspicious start,
advice please, thanks joe
