problems with installing edgy

[MICHAEL WEAVER]

I went to my Linux Group this evening and tried to install Edgy only I 
ran into a few problems.
The first problem I had was speech.
Someone fully Sighted told me when the prompt appeared so I could choose 
the accessibility option I wanted, It seemed to come up with the menus 
when I pressed F5, I pressed 3 and enter twice but when Ubuntu came up, 
no speech at all.
After this failed I tried installing it normally, Ubuntu played the tune 
when it starts from Live but the laptop seemed slow and took many 
minutes to bring up the desktop.
The people helping me to try and install it tried to use the icon on the 
desktop to install it and it just seemed to lock up, maybe act like it 
was doing something then just crash.
I am wondering if I have a faulty download when I downloaded it when it 
first came out as a released version and whether my problems may be 
resolved by a fresh download of the Edgy CD.
