Error when using MM after PC Reset

Hey guys, just joined this forum in the hopes of finding a solution to my problem.

I had installed Music Maker Premium last year and used it for quite some time. Then, a few months ago i reset my PC and build in some new hardware. I just downloaded MM again and get the following error:

InvalidUserIdentification, Error: There was an authentication error with the Store. To access the store, you need to restart Music Maker and log in to the store again. ServerError, Critical: Host requires authentication https://api.magix-iap.com/codo/rest/v1/bookmarks?withIds=true

Since my PC has been given a new name, i deleted my "old" name from the Magix Product Page and registered my new one. I cleared caches, deleted stuff from AppData, used "Clean up Store" and even restarted my PC, nothing worked. Does anyone have a solution to this? (The hardware i build in was just a new graphics card)

@4rt3m1s Ok, thanks. This sounds like you did everything correctly. It could be a server problem or do you have firewall/antivirus instead of Windows Defender?

Did you try to deactivate the software via the Help menu and then reactivating it again? Maybe something didn't work correctly the first time you activated the software.
