Spyware Doctor hmmm ... many spyware utilities are not p2p friendly & consider many p2p programs as spyware when they are not. It may have damaged LW. Put LW on it's safelist just in case.

I'd recommend (1) removing all Java versions, then re-installing Java using ONLY the Offline version. (2) downloading LW OFFLINE version. Then reinstalling.

The question about available space refered to your system partition, not other drives in this case.
