Help with reconnecting with DS

[kennypu]

hello,
my name is Ken and I'm the main programmer for our robots, however this is my first year directly participating in FRC.
Anyways, while I was playing around with the cRIO and windriver, learning how to do various stuff, going through tutorials, etc. At one point I was able to connect the DS and cRIO, and everything was functional (except for the camera). Now however, I can't get the cRIO to connect with the classmate anymore (the 'communication' and 'robot code' lights will not turn green). If it is possible, I may have resetted the cRIO's ip, making it not connect with the DS. I have tried to use the re-imaging tool to set the cRIO again, however the imaging tool cannot detect the cRIO. I looked around places, and I've read that you need to use something called MAX to reset the cRIO? But obviously I have no idea. Any help would be appreciated, thanks in advance.
