I too had a problem downloading it. The first time I used Netscape and after 6 hours, it was completed. Then I couldn't open it! So I did it again through IE and was able to successfully download AND open it (it only took 7 hours!) But now, it won't recognize my j2sdk1.4.0_01. It's reading it as JVM 1.1.4. Very frustrating! I emailed the company and have yet to hear from them. If we ever get this, it'll be nice! Good luck...!
