MGM Woes

[SV6000]

Hi all
I have recently purchased the 280A 6s ESC from MGM compro and i am having a few little dramas. First drama is that when i hook it up to my PC or laptop to get the SW updates it will not download the info, i keep getting an internet connection error. The Flasher program will find and update the USBCOM++ just fine though.
My second drama is that the truggy doesnt seem to have any brakes. I can set the brake and drag brake settings to 100% and it will still take a really long time to slow down
I have checked all of my radio settings and everything seems normal.
For the sake of diagnosing the system i am running is a Futaba 3pk with 2.4ghz radio, and a plettenburg maxximum on 4s. The ESC wires are directly soldered to the motor wires as the speedy came with two sets of power conductors (ordering mistake i made). As a result i have to use the software to reverse the motor direction. But what i did notice is that when programming the transmitter to the speedy i had the reverse the sevo direction as it would not recognise full forward at all.
Could anything i have done affect this at all???????
