Yes I was. Only I don't have a current version. I tried to download the up dated version from the link u sent me but I couldn't open QuickTime after downloading. The message said, not a valid Windows 32 application. Doesn't have a valid digital signature. I don't know what this means, can u help me?

I had just downloaded app today for the 1st time so it should be up to date. So why can't I still open video?
