Okay, slightly more specific error now. I have changed the permissions:

Now attempting to launch from terminal gives me this:

I tried repairing permissions earlier, actually. Just did it again now and received the same error as before, though it doesn't look like it's related to launching Maple...

Warning: SUID file "System/Library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool" has been modified and will not be repaired.
