Here is the problem (I think). When using a flash drive, WINDOWS assigns it a drive number (E,F,G, etc). When using LIMEWIRE, you are asked where to file the downloads. If you file them on the drive, LIMEWIRE will assign it the drive letter. If you use multiple flash drives for other purposes (like I do), then when you use the flashdrive you reserved for LIMEWIRE, the drive letter may be different than what is assigned in LIMEWIRE. LIMEWIRE doesn't recognize it. This happened yesterday. The flashdrive drive letter changed from (G) to (I), and LIMEWIRE did not recognize it. I had to go into WINDOWS and manually change the drive letter back to (G). Everything worked fine after that.
