"Inserting license key" hangs

I am unable to insert my .avastlic into Avast Premier! Every time I try, it always hangs “inserting license key” and it sits there for hours saying “inserting license key” If I close out the subscriptions window and reopen it, the license is NOT there nor is it trying to insert the key! I have been trying for six hours now to no avail! I tried uninstalling and reinstalling Avast and it still hangs on inserting license key!

I Googled the problem but literally nothing regarding this problem showed up like if I am literally the only one having this problem! There seems to be no information regarding this problem whatsoever!
