Change provider, how restore savedata ?


I have 2 providers : Multiplay and HFBServers
I would like to transfer the backup files that are currently in Multiplay. So I have two files: The map and avatar.bin file. The problem is when I upload these files in HFBServers, the map is OK, but not the players. They connect naked or without inventory, others connect with the character of another player.

Can someone help me?

Ok i understand.
Backup files work like this:
Each player has a file avatar.bin contained in a folder with their steamid. I need to get these backups, the problem is that Multiplay only communicates a list of all file avatar.bin without informing to which it corresponds…
