Remote problems with Clifford Solaris

I recently purchased a used Clifford Solaris alarm system and installed it myself in a 1995 Plymouth Voyager. Everything, including remote start, functioned properly via Cliffnet Wizard Pro, but the remotes wouldn't do anything. I can't arm or disarm the system. I cleared the remotes from the system and tried to reprogram them, but the alarm doesn't seem to sense them at all. Can anyone tell me what could be the problem? Is it a problem with the remotes, the antenna, or the brain?

I replaced the battery in the 16 button master remote. The led flashes on it when I press a button. The battery in the standard 4 button carbon fiber remote is fine and it looks like it wasn't used much any way.

Any help is greatly appreciated,

Mark
