Sellers can't increase the number of activations for already purchased products.
He either has to buy the EA again or he asks the Metaquotes Service Desk for help.
Gentlemen, I thank you for replies.
I went back to my ForexVPs providers and requested to restore the IP and most of the guys were able to renew my terminated ForexVPS subscription with the old IP address. This has helped me to reactivate my activation. Now I just lost 1 activation. But this has come with a cost of 3 subscription of ForexVPS active now. I will have to compensate it by putting some extra funds I suppose!
Probably you guys are old enough in FOREX but for the newbies, I would only advise not to play with EA activation with different VPS (outside of MQL5 VPS), Because 1 VPS is equal to 1 Activation. If you are not happy with the VPS services and want to change, remember you are also loosing 1 EA activation provided by MQL5.
