Invalid serial key P51

[DoctorStrop]

Help!

 

I have bought the mustang add on which, completes my collection so far... However when I try and conect to multiplayer, I get prompted "Invaid Serial Key". I have used the unbind webpage, I only have one account as ED merged my accounts ages ago. I have installed A10c and CA, have held the shift key while clicking multiplayer, and added the respective serial keys. I next tried to install P51, but when I hold shift and double click muliplayer I still get the CA serial key prompt. The same for FC3.

 

I was having problems buying Mustang, as at the time I found that the DCS web site would not log me in correctly, and I was finding it difficult for the cart to recognise I was logged in. Then when I got home I had difficulty in logging in again, and had to clear my browser cache to get in. Anyway, with all the messing on, I have a feeling I entered an incorrect key, but at the time it was accepted and I could play single player with no hiccups.

 

I am assuming that it's the P51 mustang install that's goosed it, as I was flying MP last night.

 

I don't want to have to reinstall DCS world for a second time this month.

 

Any help would be appreciated.

I've already sorted it. I had to add the file at this link http://forums.eagle.ru/showthread.php?t=94531, to the registry. I lost an activation on each which is dissapointing, but no more Invalid Serial prompts.
