ntp server missing after os upgrade

Hi, my RB333 was just upgraded from 3.27 to 4.5, now I don’t have an ntp server any more. The client is still there and working fine.
I re-downloaded the 4.5 zip file, unzipped it and tried to upload ntp-4.5-ppc.npk, but got the error “Could not change the key- invalid key”.
A look at my license shows Upgradeable to 5.x, level 4, and when I click the Update License Key button, it says “License key is up to date!”

Any suggestions as to where to go from here?

you tried to upload it to packages folder, you need to upload it to FILES folder. then it will work

Thanks Normis, it works a treat when I stop being dumb! Now I am back to an ntp server as well as client.
