Hi everyone,
I am installing Mac OS X lion 1.7.2 on my computer using KakeWalk.
I prepared the USB and Booted from it.
I got the the Lion install screen and my mouse appears to work fine ( I can move the cursor) but I can't click anything.
I cant click the continue button. Using another mouse or pressing enter on the keyboard does not work. I have tried pressing every button on the mouse to no avail.

Please help, here are my specs

EX58-UD3R
Intel Core i7 930 Bloomfield
Radon HD 5770
