trying to load new firmware A30??

[GulbadinNaib]

I am trying to update the a30 firmware. I downloaded the latest firmware file from Geeetech. I have my laptop connected to the printer and printer shows up as com3 in the device manager. When I run main, I see Com 3 at the top. I do not see the two buttons that are supposed to be at the bottom of the program (version 2.0). So when I select the mainboard bin file it gives me a green check but I can not do anything.

Any help appreciated.
