Ignore those messages, hey aren't important.
If you aren't connecting or are getting very few connections:
a) make sure you are sharing some files (to gain credits)
b) try downloading popular files (since non-popular files have very few sources)
c) tweak Preferences -> Connections -> Max Sources and Connection Limits
Have in mind that for the first few (about two) weeks, aMule will download very slowly since it will have yet no credits, but after about two weeks of sharing, it will download rocking fast! :-)
Also, please have aMule running and sharing the longer you possible can. It is recommended (in the eMule website) to have aMule runnin permanently 24h/day.
All the above is not aMule-specific, but ed2k_clients-specific, so don't blame aMule, it's the protocol's design ;-)
Greetings!
