Mickjapa and OP you still have Java 1.5 installed?? This Java has issues! You should go here http://java.sun.com/javase/downloads/index.jsp and scroll down to Java Runtime Environment (JRE) 6 download it and save to your desktop or received files. DO NOT INSTALL AT THIS STAGE now go to control panel add/remove and remove ALL Java 1.5 apps in that list including updates, after all are removed then install (JRE) 6.
Be aware that Java 1.5 and below are vulnerable to hackers attacks and viruses.
Also for your information your Adobe should be updated to Acrobat 8 if not already done
