Okay, I poked around more in these forums and tried the "revert to default" and "slots is 1 or larger" solutions, then went back and tried to download and ureeka!, it's working. Any idea, though, why my "Library" got cleared out? I found the files within my c/drive, but still curious why the library took a dive? Any ideas?

OK dancski here's the likely deal ... if you had originally had your library time limit of days to keep unfinished files at a time of more than 7 days, when you reverted to default it reset that back to the 7 day limit and the files were purged. That seems to be one of the biggest problems with using the "revert to default" feature. Anything older than 7 days goes bye-bye. In the future you can avoid that by first moving your unfinished files to another location unrelated to limewire and then and only then use the "revert to default" option in the tools.
