My 2 cents worth,if you change your system clock back this will also trigger activation issues.As i found out to my frustration,ie:repeated activation screen after validation.

thanks for the advice.. times are correct :( i will just have to keep waiting for a reply to my ticket and hopefully something will help, purchased this thing on the 4th after waiting for 2 years and still not able to fly it :( injured myself at work so cant work and now cant fly, pretty depressing!

For what it's worth, my activation didn't work until I opened TCP port 8888 open OUTBOUND on my firewall.

Jast reformatted my computer and only installed fsx with no other add ons but still the same thing...,

so, i reinstall my windows, now i'm ready to fly the pmdg 737NGX. it works! yessssss

Well that makes 2 of us.. however i found out that my issue was with the time as per what mickyfinny said above, however i had to go through internet clock in the clock settings and change it from time.windows.com to time.nist.gov Now i am happy flying :)

Hi there I've reinstall PMDG 737 on my new PC and I've got the message about EXTRACTIVATIONS, what can you suggest? 

 

Hi there! I need to istall again on my new disk  737 NG but i got EXTRA ACTIVATION warning. I think I need a new code. My registration name is Tizianosandro LENISA.

Many thanks for Your help!

For a case like this you will definitely need to reach out to the official support. support.precisionmanuals.com

You'll have to register a support account there which is separate from your customer account. 

They will be able to sort things out, nobody here can though. This is a user-to-user-forum.
