If she can log in then what files is she sending you? If she isn't sending the whole folder, then you need to patch another EP 4 server that you have with the files she send you, which have to be the:
| updater.exe |
| game.exe |
| version.ini |
Also she needs to check if she changed all the IPs to Hamachi's IP, and you need to be on the Hamachi network to be able to get on game
