Quicktime Problems...

Whenever I launch quicktime it unexpectedly quits and asks if I wish to send a bug report.

Whenever I try to watch a quicktime movie file on the apple site for instance both the Safari browser unexpectly quits as well as quicktime.

I have tried to reinstall quicktime, deleting all files named quicktime beforehand but this doesn't seem to help.

Moreover, the installation process never reaches the end, it seems to stick on the second last part in the process that states ' Processing Quicktime - Running Installer Script - Time Remaining - less than a minute'

I was advised to delete the quicktime preferences before relaunching the application which doesn't appear to work either.

I 'd appreciate it if someone could help,
Thanks.

 

Anyone at all ?

?
