I purchsed P2E yesterday (having used it for years on an old computer - I purchased new version, not an upgrade) and was promptly sent the registration key. I am having exactly the same problem Galatas had recently - in the "Pictures to Exe Deluxe 6.5" start up box I hit "Load a key". I then paste the key (with top and bottom lines as told in the email it came in) and click "activate". A box "thankyou, your licence key is successfully loaded" comes up, P2E then briefly opens, but then after about a second goes back to the original start up box with the option for entering a key or continuing the trial version. The only way I can get P2E open is to continue the trail version - which of course does not let me do everything (and presumably will collapse after 30 days). I read in the Galatas thread that the start of the key was incorrect. My key has only the 3 letters "PTE" on the first line. I tried copying the longer first line you gave Galatas, but that also has not worked. I am about to go away for a month, and was hoping to get some slideshows done before I go... any quick help would be great! Thanks.
