Do the Bug Report test again & what does it say? If it still says false then there's still something blocking LW from having total access.
Are you sure you configured all your firewall s for LW's total access including your XP firewall.? See instructions here:

How many incomplete files do you have?
Are you in the habbit of using the Resume function? This can be quite effective, however, as a general rule, it should not be applied to too many files at once, else you're going to have files queuing for much, much greater lengths of time & it can play havoc with your connection quality.
There's something else you can try. Make a note of all your settings in LW. Then close the program & delete the LW Preferences folder called
.limewire It's found here:
C:/Documents And Settings/your_username/.limewire You will need to reset all your options again after deleting this folder. Which version of Java are you using?
