Yeah, like bungiefan said, from your previous computer, export the registry file from HKEY_LOCAL_MACHINE\SOFTWARE\PlayOnlineUS. I can send you my registry file if you don't have a system that you can export from if you want. Next, copy the files over to the same folder tree. Run the registry file you previously exported. The last thing you need to do that bungiefan didnt mention, is you need to run regsrv32 on the dll files to be able to play.
create a new text file named something like pol.bat (not pol.bat.txt, make sure the extension is .bat) and inside, have this code:
Code:
FOR /R %%G IN (*.dll) DO regsvr32 %%G
Stick this in your POL folder and run it, it'll scan the folder and subfolders for .dll files and register them. If you're using vista, it's a bit more difficult, but still possible to use this or a similar method. It's also possible to transfer files from an xp system to vista, but also yeah, requires more work and is probably more hassle than it's worth. If you don't register the dll files, I get an error saying something like POL isnt installed.
Also note that doing it this way can cause bugs. On my vista system, it won't allow me to sign on as a guest anymore. For some reason, logging on as a guest won't connect to POL.
