R6025 error when creating slide presentation

Hi,

I’m a newbie to Flash working in Flash CS4. I’m able to create all types of files except for a Flash Slide Presentation. As soon as I create a new presentation I get a R6025 Pure Virtual Function Call error, a message pops up saying Flash has unexpectedly quit and then the program hangs until i have to manually end the program in my task manager.

I’ve tried to find out a bit more but it sounds like people only get these errors pertaining to their browsers so not sure what this error has got to do with Flash CS4.

Any ideas to what I should do to fix this as I need to create a presentation urgently. The rest of the application works properly.

Thanks
