Question: Starting Maple 12 on OS X; successful install, program will not launch

I'm running OS X 15.5 and have just installed Maple 12. I cannot figure out how to get this thing to launch. If I attempt to launch Maple from the surface in the applications folder, the Maple icon bounces once on my desktop and then -poof-, it disappears.

I have also tried running it from the command line thus and received a permissions error:

dhcp0918:~ emcdowell$ /Library/Frameworks/Maple.framework/Versions/12/bin/maple
-bash: /Library/Frameworks/Maple.framework/Versions/12/bin/maple: Permission denied

and have also tried this:

dhcp0918:~ emcdowell$ cd /Library/Frameworks/Maple.framework/Versions/12/bin
dhcp0918:bin emcdowell$ ./activation
-bash: ./activation: Permission denied
 

...Can anyone help me out? I have no idea what's going on. I'm a unix baby, so I really have no clue what to try next.
