Dox: That unreg patch actually works fine on my side, creates a TWEE_Upgrade-Unregistered.exe. But it still wants to go online to register and thats the problem. ive been working on a way to get to not want to register but i cant crack the patchsecurity.exe or the setup.inx file.
Those 2 files are part of the extracted TWEE archive btw, which can be extracted using universal extractor.
It's just occurred to me that while there are differences between the US and International versions of the game. Their is only one version of the TWEE_Upgrade.exe files. Typically the patch has either worked or errored. If it's errored the above fix should work.
Is it possible you could try it on another version of your TWEE_Upgrade.exe file.
Also it shouldnt want to connect right? It should just indicate that the game isnt activated? Although after the patch it does this and then reports it is activated even though the servers are down.
Other than that, I dont know, most of the people I know of had the error and this fixes that so it must be another issue.
EDIT: Just checking your not applying the EE patch and then trying to play are you. If so you will need to apply the 1.5 patch to remove the DRM.
