Before starting AfA_OS make sure that your screenmode is set to truecolor (24bit). Afa_os_iconlib and skinning won't work without. It is likely that your system crashes badly if you try though.
Move "c:morelibspace REBOOT" to top of file, just to be sure nothing else interferes here.
I've checked the wrong assignment you set to Afa_. Surprisingly this doesn't stop AfA.
There must be a typo elsewhere, if a "wrong argument" pops up.
I don't know what causes Iprefs to crash.
For error checking please set a ";" (no quotation marks) infront of every line from AfA setup.
e.g.:
;c:morelibspace
;Assign Afa_ .....
;c:Afa_os_loader

Reboot and check if WB starts correctly.
What's your Kickstart version? 3.1 is required.
Cybergrfx or P96 running fine?
Check files and folders. Are all AfA files copied properly?
And a personal note:
If you copy&paste scripts, batch files or code snippets then use "#" from toolbar to wrap it for better readability.
And finally, this a forum. It's not a chat, instant messenger, hotline or your personal help desk. If you impaciently insist on help or answers you'll get quite the opposite of that. Nobody will help.
