Couple of things. Are you turning on your transmitter first? The second set of beeps is when the tx/rx are both on, it beeps to let you know it is armed. If you are still having problems you should try to reprogram the esc. Do you have fresh batteries in your tx. Hope this helps, good luck.

You said you can make the truck go with the steering output, but does the throttle then steer fully? In other words; switch them around.

I agree with Cartwheels; re-program the ESC. Not all the options, just the transmitter part, which is easy to do. FYI: You should reprogram the transmitter to the ESC after making any changes via the PC software (according to the manual and experience). Set your throttle trim to center and your EPA to 100% or more first.

If you bumped your throttle trim and it is somewhat in the forward range when at rest, the ESC might be thinking you want to enter programming mode since that's how you enter programming...
