Well I am running Kaspersky Internet Secruity 2010. and my OS is 64-bit Windows 7 Professional.
And how much more disconnected can it be if it's my internet cord is on the floor (my computer is about 3 feet off the ground on a desk)
Kaspersky proves to be troublesome at this point because it blocks nearly everything. So my advice is to turn off proactive defense or add that folder ("My Trainers" to its exclusions list.
Also in your "My Trainers" folder, do you keep the trainers themselves or their shortcuts?
If you are done with the above two, and still encountering the authentication problem, I advice you to disable UAC (User Account Control).
