Flight ending enroute

[aggu]

Hi, I have purchased the full version thru simmarket, however about an hour into my flights i am getting an error telling me to buy the full
version of fsp. It is sporadic and occurs once out of every 5 flights and will recurr from the same airport until i move to a different airport.
Seems to be with the large US airports, KRDU, and KLAX currently give me this error everytime i take off. Havnt tried many other US
airports. Landing at the airport is ok, but if i turn and take off from that same airport I will get the message to buy full version.

thank you

Did you unlock your version of FSP?

Oh yeah, I've been flying for a while. I have uninstalled fs and fsp and reinstalled both including the update for fs. Unlock is successful as
it allows me to take off and fly for an hour without any warnings of not having unlocked version. As well I do have successful flights with fs
from other airports, just seems to be the US ones I have tried. I have not copied the files from previous install, I am using a fresh install of
fsp.

Reboot so xp is not holding any files
reinstall fsp
unlock
and try again.

I had the same problem when i formatted pc once, some flights were ok, otheres i would get the please buy message, after doing the above, its worked
fine since.

I had to go one step further and to delete all FSP files and folders after uninstall, clean the registry and do a reinstall. No idea why but the
next time I did a reinstall all went fine and I didn't have to do a thing.
