I already sent you a reply on one of your previous posts at March 24, 2001. It says:
Make sure you have the Update 1.2 installed. If not, go get it at ftp://ftp.lucasarts.com/patches/pc/J3DUpdate1.2.exe - you'll get an EXE file which you simply double-click, it installs itself.
Next, download the savegame which I put on my ftp server for you. This will enable you to overcome the problem. There are two files at ftp://ftp.soulianis.com/archive/indy/ - the original savegame (.nds) and a zipped version (.zip) - you need WinZip or pkunzip for the zipped version but it is much smaller and therefore you save a lot of download time.
