compustar 2w900fmr problem

I have the Compustar 2w900fmr and it has been installed for awhile. I used the remote start this morning and it worked fine. When i arrived at my destination, i tried to arm the alarm but no response. I thought it was the battery so i replaced it and still nothing. Usually when i start my car, after i press the brake pedal the doors lock. Now nothing. Its like the alarm isnt getting power. Any suggestions? Im not sure if it has a in line fuse or not. Everything else in the car works radio, lighter lights, etc. Any help would be appriciated. Thanks

There are fuses in line with the +12V and Ignition. Should be RED and RED w/WHITE. There is also a fuse on the park light output (GREEN w/WHITE), but that wouldn't prevent your alarm from responding. Check those first.
