Just installed bf2 everything worked fine, tryed to do the patch and it gave me an error but still started fine but there were a few menu labels messed up, tryed to install POE and got an error GRR.
Edit:
Well heres my experiance with reinstalling BF so far:
---First try
Install BF2,
Install Patch 1.3,
Install patch 1.3 and get patch failed error,
Run BF2 and it seems to work but with some label errors,
Intall POE v1,
Run POE - Label errors still there but try to connect to servers anyway and get LOCERROR cdkeyinvalid error,
Uninstall POE then Bf2 and delete any folders left over.
---Second try (Redownloaded Patch 1.3)
Install BF2,
Run BF2 but get windows error (send log to windows thing, "Dont send" of course

),
Uninstall BF2,
Delete any folders left over.
---Third try
Install BF2,
Run BF2 and get the same error,
Install patch 1.3 and get patch failed error,
Run BF2 and get the same error,
Uninstall BF2,
Delete any folders left over.
Whine on OCUK about it.
