Recently I got problems when starting Ulead VideoStudio 10 Plus (or VideoStudio 11 Plus) from the main panel of VideoStudio (Editor, Capture,DV to DVD). The message is:
The instruction at 0x0774415b referenced memory at 0x00000000 The memory could not be written.
Contacting Ulead (Corel) and following their advices (checkdisk, disk clean, remove every temp files, Ulead directories, etc.) did not solve this nasty problem (they suggested to reinstall from scratch Windows XP, but I'm reluctant to do it): it used to work fine a few weeks ago.
System: Dell Inspiron (3 years old), 512K mem, Windows XP home with up to date updates, more than 35 GB of free space
