Contract trouble

I'm really new to Adobe and i'm struggling a little. I just got my first contract signed by a client through Adobe and i'm trying to download it to my computer for safekeeping but the option is greyed out. I tried to download it as a PDF and it won't let me do that either. When I checked the security on the file it said its security was password security. I didn't set a password and now I can't change it even though I am the author. I could get the contract signed again while double checking the security level but I don't want to put my client through that if I don't have to. Any advice before I contact support or get the contract signed again?
