Had this issue before. Are you disabling your CFW syscalls by any chance (Webman or PSNinja or whatever it's called)?
If you disable the CFW before changing the IDPS in Rebug Toolbox, the option will be on "No" and you won't be able to change it (it'll give an error about unsupported FW or something like that).
I remember disabling syscalls. I actually don't know how to re-enable them

but it still isn't giving me a message. Should I try selecting DEX like it usually is?
