Problem installing setupdsv201.sh

Hi

I've tried to install setupdsv201.sh in my PCs under Fedora Core 8 with no success. I have a Core2duo machine, with 2GB of ram memory. It also has Nvidia Gforce 7300GT video card. At the moment it is working jre-1.7.0-icedtea.x86_64, but I also tried many others(for 32 and 64 bits). The problem is: when the first installation windows appears on the screen it hasn`t any text. So I can not follow the installation windows guide. Is my video card supported by DS? What could I try?
I've been able to install DS (with the same downloaded file) in other PC (32 and 64 bits processors) under FC8 and much older than mine.

Any suggestion will be appreciated.
