Serious Error Xtreme Pro 5.0

[gramme]

Hi,
I use Xtreme Pro 5.0 and it has been working just fine. Today I needed to do some work on a .jpg file. I imported the file and tried a copy paste and got this error message. I am uploading the screen shot of the error message.
Can someone help me please I really need to use this program.
Thanks
