As it wasn't a very smart move posting your Order Number on the forum (haven't you noticed I've edited it ?), it was even less smart posting your Serial Number, someone might steal your activations with that info. If you need to share that informations, use email or private messaging.
In any case, the 25001 error code simply means you typed your Serial wrong. And, in fact, checking the failed activations log, I can see two failed attempts coming from your ip number, the first one you typed the Serial almost correct, except you put too many "zeroes" in the initial part, after C9F4F1. On the 2nd attempt, you put the correct number of zeroes, but you haven't typed the last but one group of 4 characters.
As with any other software asking for a Serial Number, if you put the correct one, it will work.
