MT4 terminal will not open

Hi there, 

I am having a problem opening my MT4 platform.

After having downloaded it about a year ago I uninstalled it but I have recently reinstalled it.

I am using a Mac OS so I used Wine to install it. It all seemed ok but every time i try to open the terminal it comes up with a message saying "the program terminal.exe has encountered a serious problem and needs to close". 

If anyone can help it would be much appreciated!

Many thanks,

David
