You know what I think is going on? Check this out. When 1.6 came out with mention that after 1.6 install one could only to back to 1.5, I have a feeling that the 1.5 that was at the website, from that day, was no longer backdateable. A modified 1.5 perhaps. Maybe, just maybe, if I can get ahold of an "old" 1.5, that would work. This very well could be the problem.
