that's quite strange, the installer works faultlessly in 5 computers I tested (A2000, A2040, A2060, A4040, A4060T)...
My Janus version is 36.83... it must be installed in sys:Expansion
you should have the command BindDrivers in your Startup-sequence, so the Janus.library will be loaded.
Try to boot without caches to see if the janus.library loads... the CPU caches sometimes give problems with bridgeboards.
Check that the board is recognized (you can do this with sysinfo for example, if the board appears, it will probably work)
