the reset logic of the software is active

Hi everybody, my name is tjandra,
i am 37 years old and came from Indonesia.
sorry if my language not too good.

i've just buyed stepcraft 840 v2 ( from 2nd hand market ) with the uccnc as the software (but the software is original with the machine).
i already tried about 1 weeks until i found this forum, i also asked my friend, but they dont know..
does mr/mrs administrator or anyone out there can help me, i really need help..please..

my problem is with the uccnc software cannot press the reset button, i already check : the blue led and the yellow led on the machine is on, and also the yellow led in jack adaptor is on.
i didnot hit the maximum limit of the axis.
my friend already make profile icon (in configuration create new profile)for the uccnc, so when i load the profile and if i click reset. the message is :

the reset logic of the software is active!
remove the reset condition with pressing the blinking reset button on the screen.
if the reset condition cannot be removed can be due to an external e-stop button is pressed in or a limit switch on the machine tool is active. please check the diagnostic page for the input signals condition.

when i click diagnostic the I/O monitor :
O5 & O9 RED
O16 RED BLINKING
I10, I11, I13, I15 GREEN
The rest is grey

but if i start the program from uccnc software ( not from the icon profile on desktop ) the reset button can be click and the x,y,z arrow appear but if i click, cannot connect to the machine
i already check cable and the other.
i already check fan belt to move x,y axis ( my friend told me when adaptor is on, you cannot move the fan belt because there is power from dynamo motor, but in this condition i can move the fan belt )

please for anyone who read this message can help me to solve my problem. 🙁
thank you very much.
