I was doing a map in Radiant.. I save it and compile... after a while I opened Radint again and it says an older map version(I think its that) was available and my map would be saved in a bak file.. so I click yes.. it loads an older version of my map.. so I changed the .bak file to .map.. and it loaded THE SAME MAP... this means I lost everything? I must do everything again? pls someone help me!

Sorry to say that,but yes.The .bak is kinda of a backup.Next time backup you mapname.map in another folder of your computer
