Upgraded NIS to v22.xx and now it won't "re-activate"

For gods sake why is it so much f'ing hassle

I have just supposedly upgraded from v21 to v22, should have around 9 months left on this years sub and it wont activate

the error message is "We're working to resolve an issue that prevents us from completing your request. Try again later. (-6)"

so what do I need to do with this crap???:??!!!!!!!
