Lets try to narrow down the problem and find the root of it...

Are you behind firewall ??? As i can see that you can connect to tracker cauz ur profile and those threads show that u are seeding.... If you are using windows firewall .. there is an option in utorrent preferences to add exception in windows firewall... also try exiting any other firewall (if u r using any)

Is your ISP chaching/blocking utorrent traffic ??? if yes, try enabling encrytion.. it is in speed test option (ctrl+g)....

i downloaded ur torrents and i m unable to connect to you either... ...

lastly , are you using some corporate network ??? As you isp might have blocked utorrent..

i dont think you are getting any errors in general -> tracker tab.. but just recheck it .. wanna make sure that you are not getting any other errors... If there is any error there.. lemme know..

In short, this seems like either ISP or firewall problem..
