Tracker errors, please help

[Mentos]

Hello, Im a newb to these forums but have been using utorrent for over a year now.

I recently followed this video on youtube:

And to my success, it DID increase my download speeds substantially on torrents I already had running in utorrent (using newest version).

However, whenever I added a new torrent, REGARDLESS of having numerous seeds per the tracker, I cant connect. I tried restarting utorrent, and then ALL torrents (including the ones that were downloading fast before I closed it) have tracker errors now.

Help! What do I do?

EDIT:

So right now, I dont CURRENTLY have tracker errors, however, I still cant start new torrents Ive added. Whats wrong?

EDIT 2:

I apologize, I meant to post this in the troubleshooting section. Could a mod please move this?

Once again, I apologize.

Also, the error Im getting is that they've all "Timed out." One says invalid URL for one tracker, but all trackers are timing out at this time. How can I fix this?

totally insane values this guy suggests!

press CTRL+G and use in the drop down menu the value for what your UPloadspeedline is capable to.

This will set automaticly set reasonable values that can (and will if the swarm is capable of providing such speeds) max out your downloadspeed.
