can someone break down bittorrent errors

for example, im getting one that says..."no data from tracker" or something...

which errors mean you might as well pick a diff version of the file and which ones mean just be patient and someone else will eventually sign on and you can download?

 

when you have that message "no data from tracker" this happen when the server go offline you can wait to come back on or choose another tracker....

hope this help....

 

i use azarues (sp) but lately ive been getting a lot of errors or slow speeds. kinda sucks...
