You can reset the player bu holding the enter button for about 30-40 secs.
This often fixes problems
In your case you could try that if that doesn't work check if you upladed the right firmware(T for TP players, S for SP players)
As your player is new its probably an SP
Don't worry too much about the player though. This problem can be fixed
First try to rest, if that doesn't work try a format(see manual) if that doesn't work you could resort to DFU tools as a last option
