manuelbp,
Check your device profile settings. It might be configured as a dialup by default. I *think* that when you communicate with the UD Server that it tests your up/down throughput. However, if your profile is configured as a modem, it might be a moot point. Try changing it to be isdn or dsl or something. See if that works.
I did recently change my hard drive allocation at home. I think I bumped it up to 8 gig, but the program doesn't seem to use any more space than before (as of yet). This increased my storage rating to like 178 (it was 20 prior to that, at 1 gig), and gave me an overall over 30(?), was 25 before.
