As long as you have flash and XP there can onle be a few things that will prevent you from viewing the clips.
#1 Firewall or security settings may need to be adjusted.
#2 Hardware - You need at least Intel® Pentium® II 450MHz or faster processor (or equivalent) and at the very least 128 meg of ram.
#3 You need explorer 6.0 or greater if you are using a PC.
#4 Hard disc space - our big clips need about 100 megs of hard disc space. If you're running out of hard disc space that is more than likely your problem.
