i had this problem too but i am on linux but anyway the problem was fixed simply by installing the latest flash program i had to open the ports and stuff to but if after all that it still aint working right check your flash install

as far as messing up your share ratio i read some place (forgot were) that the latest distro is got something that messes with that try down grading on the homepage they always have the code for old distros since it is an open source program
