Update issues
A lot of antivirus software was flagging the updater as malware.
Most of them have fixed the false positive. The rest should fix it soon.
If you're having an issue updating, either add all of the SiQregSpin files to your antivirus allowed list, or you can just download directly from
https://siqsoft.com/downloads and move the new SiQregSpin.exe into your old SiQregSpin folder (to keep your settings).
Registration issues on .es
So the fix I made for .SE and .ES apparently fixed a problem for half of customers and created a bug for the other half. I've made a new fix, and I'm waiting for feedback from testers. If you want to test it now you can email or PM me here and I'll send you. But if I hear back from the affected testers soon then I'll be pushing another update soon.
