can't register flash fxp

I own flash fxp and just installed it on my computer after reinstalling the OS. The program will not accept my serial number, insisting that it is wrong. Please help.

in order to use 3.7.9.xxx - you have to have an older version of flash installed first and register it, then install 3.7.9.1389, this will allow you to register the beta, then you can update to the latest beta release

Hello,

These beta releases are only available to beta testers.

Since your not a beta tester either you selected the wrong version for your bug report or you downloaded it from some place other than our website which is NOT recommended.

Also if the file has been modified 99% of the time they will void your license keys.

Registered users should never use copies of FlashFXP downloaded from 3rd parties.
