Thanks. I now get to the store, but it gets a 500 Internal Error trying to verify my key. Also, the Purchase link does embed my Arq 4 license key, but in the form, the upgrade license key field is empty, and I have to find it from my old .arqLicense file and paste it. I don't even know if I'm copying the right thing.
Same here. Let me know if you figure this out. I'll do the same. I just shot Stefan an email but I'm sure he's inundated at the moment...
Having same key verification problems too. Will try again tomorrow!
Still having the same problem today...
They just added a "Retrieve license code" link on the web site below the Arq 4 license code field. I was able to upgrade no problem. FYI.
