Is there a way I could convert the current map back to the old format and then load it on tekkit ?

I just installed Tekkit as my new server client but I'm having a bit of trouble. For some reason I have no idea how, the map I've transferred over from my current server client (bukkit & Spoutcraft) is refusing to load to it's current progress. For some reason it keeps loading a version of the map about 3 months old. I have no idea how it's doing it. I literally took the world folder and exchanged it for the one in tekkit. There's no backups in there to my knowledge. What's the explanation for this and how can I fix it ?
