OK, I hope this is what you need...
I am running Windows XP Home Edition SP2 off my schools' wireless internet service. We currently have a wireless network as well as a VPN. My wireless LAN card is a Dell TrueMobile with 11 mbps (or something like that). Have a Java Plug-in v 1.4.2, and 2.19 GHz, 384 MB of RAM. I THINK my modem is a PCTEL 2304WT V.9x MDC. 21.35 GB of free space on my hard drive.
As for the Java downloading problems, I can get almost all the way through the process but an error pops up everytime: ERROR 1311. Source File not found: C:\WINDOWS\Installer\MSI20.tmp. Verify that the file exists and that you can access it. Looked around for it, used search function for it and could not find.

Let me know if you need more information, and thank you so much for your help!
