Bought used ShopBot with EMC2 - worked prior moving it...now not so much

Hi all. I bought a 48x96 ShopBot at auction that had been converted to run EMC2. The guy left it setup and plugged in and saw it running and was able to use the keyboard to jog and I didn't give too much thought to what questions to ask or anything as I had used a ShopBot a few dozen times with the software they developed...well... after taking it apart enough to move it and re-assembling, I have no idea what to do. I've turned it on, opened EMC2 but the e-Stop remains on. I tried F1 then F2 but most of the buttons remain greyed out. I have tried looking through this forum and frankly, I don't understand anything. Can anyone maybe tell me where to start? 

Definitely sounds like a wiring issue pertaining to the E-stop. Maybe you swapped some plugs or wire connections wrong. If the machine has a mechanical e-stop button, make sure it is pulled out (many you have to twist to release). Or if it has an e-stop cable, those usually have a reset button that must be pressed or pulled out and the cable tension must be properly adjusted (and is usually easily pulled out of adjustment when moving the machine.)
