I am a noob to this whole BTC thing, so please bear with me.

I reformatted my computer and lost everything on it. I decided I want to restore my multibit wallet but I only have the following info:

Secret words
Old password
I do not have a backup of the wallet file or whatever it is called.

My question is, how do I reopen this wallet with that information? It has a lot of BTCs it in and I really want to salvage it.

Thanks for reading!
