NEED HELP on Macbook crash

[dinoyolk]

I recently downloaded Obsidian Menu Bar on an old Mac OSX Leopard. Worst choice of my life. Now my menu bar is transparent and every time I click on it, my computer freezes and refreshes the screen. The same goes to everything that I click on.

I tried putting in my install disk to reset it, but after a while my disk just pops back out... what can I do. I am really frustrated right now.

Thanks

The problem can be easily fixes (I think), startup until you reach the logon screen, after inputting the password and instantly after hitting Enter hold the Shift key, this prevents any 3rd party software from loading, if the system is stable now you can then open System Preferences>Users & Groups>Login Items and remove the program from it.
There is another way, startup and instantly hold the Shift key, this will get you into Safe Mode, only Apple Software is loaded, login and remove the offending software.
