Adobe CS5 on Mac Operating System getting some trouble

Hi,
I am running Adobe CS5 on my Mac Operating System but I am getting some trouble from last days. When I try to open Adobe Fireworks CS5 on Mac OS the program does not launch and the following error message displays on the screen. I can’t understand this issue. I have searched the solution from forums but could not get proper resolution. Any help would be greatly appreciated. Thanks in advance.

Fireworks cannot run. A parameter was incorrect
