We had a similar problem that started with the download of the cRIO firmware. It sounds like the IP address of your cRIO was reset to 10.0.0.2.
Get the Control Systems Configuration Guide (Chapter 5 of the Control Systems Manual) from the FIRST site. The cRIO firmware download instructions start on page 4. Make sure you set your team address before you do the download.
Hook up all the components as shown on page 6. On your laptop open a cmd window (start, run cmd). Use the foillowing commands:
ipconfig (shows your laptop address)
ping 10.xx.yy.02 (xx and yy are your team number. This shows the cRIO is the correct IP)
ping 10.xx.yy.01 (Shows you can see the bridge from your laptop)
Hopefully, this will get you started back up.
