Your settings sound ok. Are you checking for uploads by looking at the monitor page or from the library? If you go to the library & check the Uploads column...figure on the left shows successful uploads while the figure on the right shows attempted uploads.

If you're concerned, send me a PM with your IP address & port (click on Direct Connect tab, below Keyword, on the search page & this info will show)...I'll direct connect to you & see whether I can download from you.
Don't post your IP in the open forum though!
