X-AVIATION - activation problem

[Bulva]

I have had and used IXEG737, IXEG737Plus and MU2 for a very long time.
A few months ago I changed my computer and everything was OK.
However, they currently cannot log in through X-Aviation.
The first stage is OK (email and password), but when I try to go through the window: "Name and Authorize this Machine", I get the message: "machine ID locked".
What can I do???
Three planes I paid for have become useless.
X-Aviation support is silent, although I sent a request to activate my account a few days ago.
Is there any other way to be able to enjoy planes again ???
