Donald,
Assuming Sonar Home Studio 4 XL was installed normally (with the default disk locations). It installed the sample audio loops onto your hard drive-- and that's where you want to load them from. Files on the installation CD are likely compressed and not directly accessible inside Home Studio. Anyhow, look for the loops in C:\Program Files\Cakewalk\Sonar Home Studio 4\Sample Content\Audio Loops\.
