FSX PRODUCT KEY NO WORKING ANYMORE ON MY NEW COMPUTER

I'm not sure how your problem was solved, Ricardo;  was it that Microsoft removed the restriction on your re-activation?  And now you are not able to fly for more than 15-30 minutes?

If this is the case, then you can try the following, provided that MS have removed the restriction for re-activation:

1. Close FSX and run Registry Editor (press Windows key + R and type   regedit    and     Ok)
2. Expand the following registry key, but be careful when doing this as any wrong or deleted entry could cause other problems to your computer.   Back up the Registry, if you are uncertain.   Expand this Registry Key:         

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e967-e325-11ce-bfc1-08002be10318}      

3. After you find the folder, double-click Upperfilters on the right side.
4. Change the value from 0 (and delete any other word there) and type   PartMgr  (note, this is case sensitive;  type it exactly as shown here) and click OK.

5. Close Registry Editor and reboot Computer.

6. Start FSX and check whether the Activation box comes up.

Let us know how you get on with this.

There seems to be a limit on the number of times you can activate FSX within a quarter.   MS have published the following;  Issue No. 2 seems to apply in your case:

https://support.microsoft.com/en-us/help/960480/solve-problems-with-activation-issues-for-microsoft-games-and-mapping

Those with this problem (with FSX) usually have to wait three months to try activating the Sim again.

If you can't wait that long and don't mind switching Sims, then FSX-Steam Edition is an updated version of FSX Deluxe with Acceleration pack and needs no activation, except for initial activation in your Steam account.  They have it at Special prices from time to time.
