[Help] Corel PHOTO-PAINT 11 + can't open file

Does anyone have any idea as to why I can’t open one of my Corel PhotoPaint
Images? It has been saved as a CPT file and it was working perfectly fine and now I cant open it.

When I click to open it, it comes up with the warning message…

“Cannot Load. Try opening the file using a special filter”.

Does anyone have any idea of how I can open this file. I really need to open this file, its urgent!

I would REALLY appreciate any help! Thanks.
