Hello and welcome to the forums, stilivn. You should run Software Update to make sure your version of Mac OS 10.3 and software are up to date. Apple recently released Mac OS 10.3.6 awhile ago that addresses some issues. Go to the Apple menu and come down to Software Update. I just downloaded LimeWire Basic and it downloaded and mounted fine using Safari version 1.2.4 with Mac OS 10.3.6 installed. I hope this helps solve your problem.
