Hello movteka,
Sorry you are still experiencing these issues with your U-Mix!
As daniel mentioned, we no longer have the resources to troubleshoot or repair these due to them being legacy products.
I will ask the rest of the team if anyone knows of a way to do a factory reset to the firmware, or if that is even possible at all. I tried to do a bit of research on it and couldn't find anything, which makes me think it might not be possible.
If you still have proof of purchase for Cross we can issue you a new license. Since your original license was on a physical copy of Cross, we have no way keep a record of which license belongs to which user.
Which is why we registering your license/serial on the forums is so useful. It keeps a record for you and allows us to retrieve licenses if a user cannot access their account.
Please send your proof of purchase to
support@mixvibes.com Best regards,
Adam @Mixvibes
