CODE Rexx problem

I?ve recently upgraded from 5.1 to 5.1.2.6 and now none of the CODE Rexx macros 
seem to be working. I know very little about Rexx, but I know it is how the 
editor gets customized. Therein is my problem none of the customizations work. 
The code doesn?t color code and I can?t use SEU type commands, etc.

 Upon starting CODE I get error ?Error running command ??MACRO SEU?? on line 12 
of C:\WDSC\Macros\profile.lx.? I?ve since discovered that there is Macro log 
window, in which I found a series of ?REXX is not available.  Request ignored.? 
errors.

 I found rexx.exe in C:\WDSC\system and ran it and got an error that it could 
not start because REXXAPI.dll was not found. A search of the hard drive didn?t 
turn it up either. So I am thinking reinstall? Is there anyway to just 
reinstall rexx? Or, other is there another solution? 

Thanks,

Jim
