So the board works. I used the schools JTAG cable and everything downloaded and worked perfectly. So the board is good.
Good news! Knowing this will save you a lot of time and trouble.
Either the cable or drivers or both. Not sure how else to troubleshoot the cable problem.
There is more than one "USB JTAG cable". Useful details include:
- Which "JTAG cable" make and model works, and which one does not.
- Which versions of software and drivers are used.
- Which operating system is used.
Or simply go to the Xilinx or Digilent website and download the latest software and drivers for your hardware. Try the Digilent Adept tool if you have a Digilent "cable", and try the latest Xilinx iMPACT tool (and driver) if you have a Xilinx "cable".

1. Read the manual or user guide. Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts. If I write a good post, then I have been good for nothing.

Ok so I wanted to update in case anyone had this probelm. to show how to fix the problem. I have and am running windows XP.
I orignally started with the JTAG USB cable I knew there was a problem but didn't know what since I bought a used starter board. so it could have my board or the cable. I later tried my board and JTAG on another persons computer and worked fine (windows 7). I also purchased the JTAG HS1and my fpga board worked even with the automatic windows download on my XP computer.
so this lead me to believe that it was a driver issue on my original cable and not the cable or the board. Even though windows automatically downloaded the driver for the cable this did not work. I noticed that everytime I pluged in the cable it wanted a driver again.
So I did some research and came up on how to find the missing driver. Here.
After that my FPGA now works on MY computer and can now work from home.
So original issue of non programming of the fpga and SSEG lighting up only was a driver issue using Windows automatic driver download.
