Battlefield 1942 - Invalid Serial Key

EDIT: This process was now automated. If you encounter the "Invalid cd key issue" please run repair (right-click on Battlefield 1942 in Origin). For more information please see this post: http://answers.ea.com/t5/Battlefield-1942/Battlefield-1942-Invalid-Serial-Key/m-p/179498#M139

Ok, I finally got mine working ! 

1) Click start menu, type regedit in the search field (or hit windows+r if you do not have vista/7) 

2) Navigate to the following section(s) depending on your OS, 

For those of you that don't have an Origin folder located in either of these two locations: 

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Electronic Arts\Origin\Battlefield 1942\ergc (FOR 64bit OS) 
HKEY_LOCAL_MACHINE\SOFTWARE\Electronic Arts\Origin\Battlefield 1942\ergc (FOR 32bit OS) 

3) You need to create it yourself. I have Win 7 x64, so I made an Origin folder (also known as a "key" in the registry) under Electronic Arts. 
To create this "folder", right-click on Electronic Arts and then choose "New" and then "Key". Now it should allow you to give it a name, rename it as Origin. 

4) Next, right-click on the Origin "key" you just made and again pick "New" and then"Key". Give this new key a name of Battlefield 1942. 

5) Next, right-click on the Battlefield 1942 "key" you just made and again pick "New" and then "Key". Give this new key a name of ergc 

6) Next, click on the ergc "key" , on the right hand side you'll see it has a string value called "Default". Right-click it and then choose "Modify". 

Now you need to copy your product key from Origin and paste it as the new modified value. 

To find your product key, right click Battlefield 1942 in Origin, then choose Game information/detail, and you should see your product key (listed on the right hand side) 

7) You do NOT need to include spaces, just copy and paste the key and click on "Ok". 

Now you can close the registry editor, run your game and you should be able to connect to any server. I managed to connect to my dedicated server at last after I did this ! 

Hope it helps you guys :-)

Hey all,

Great news. We've identified the configuration error that was causing this and fixed it.

If you are still in this state there is no need to edit the registry to fix this now.

In your Origin My Games tab, right click on the game tile for BF1942 and select Repair Install.

This should resolve the issue. See you on the Battlefield!
