After a year it becomes unsuitable... but for me it's a fairy tale

No emails No further contact

and I wait it's normal?

I have an expired VPN subscription for 10 users for a year that I've always used on

PC with WinXP

PC with WIN10

2 android phones

On expiry, not using all the accesses, I buy another VPN subscription for 5 users for two years, insert the serial number in my account and connect the main PC and two android phones

Now in my account on the official website there are Current subscription, but showing 10 users instead of 5 Expired subscription, WITH THE SAME SERIAL NUMBER

the current subscription is seen on all PCs and phones, but on the XP one I can't switch between the old subscription (now expired) and the new one, I am given an unexpected error code.

With difficulty I contact assistance and change DNS, I redo all the setup procedures several times and I can't do the remote access, the problem is settled with an "incompatibility with windowsXP"

I asked for their intervention to reset my account, given that both subscriptions have some quirks such as the same serial number and the wrong number of users, but despite various chats and emails they have not been listened to..

How can I do? TnX

I believe that basically it is only a problem of the account and not of the software, which in a year of use I can only speak well of it

But honestly I don't know what to think, since they closed the chat talking about an incomprehensible incompatibility
