Articulate 2 GREY EXCLAMATION MARK (GCOD) on my new computer

I have published my project multiple times and every time I play the published swf it crashes and shows the grey exclamation mark half way through the project.

I was thinking that my pc might be running out of memory, but Task manager shows that the flash player uses 5.2% of CPU and 558.5 MB of memory which is less than 10 %.

Can anyone help me to figure out why does the swf keep crashing roughly at the same point always and how can I get around that.

Thanks
