Pockets wizards not communicating?

Hi. I'm having issues with my pocket wizards. I'm using a nikon d700 camera and I have 2 FlexTT5's and 2 SB-900's. I'm trying to use one flash on camera and one off at the same time. I have done this in the past and had no problems. Today, I'm using the same settings that I usually use on my camera and flashes and the flash off camera will not fire. It seems as though the pocket wizards are not communicating or something. Any tips/suggestions? I'm getting so frustrated! Lol.

Which older dslr to buy?

Just for fun and some experimenting I was wondering what are some fo the best or better older dsrs preferably 6 MP and up but if there's one that is superb that is under go ahead recommend it.
