Hmm,
The can't load rx seems to point to some arexx scripts being unable to load.
check the boot:libs directrory and confirm that arexx libraries are there. Specifically rexxmathlib.library, rexxsupport.library and rexxsyslib.library.
also check that the following files are in either the c or rexxc directory:
rx, rxc, rxset, tcc, tco, te, ts, hi, rxlib and WaitForPort.
Cheers
