CorelDraw X6 Publish or Save as to PDF Problems

Hi everyone

So i am using  X6 and i can't publish or save as to PDF anymore, at first the error was because there was background tasks that was being performed in the background so i searched the community for this and found one where i must change my settings to disable background tasks and then it worked but it took like 15 minutes to save. I opened the PDF file and everything was fine.

Now the problem is that when i publish or save as to PDF, the little process icon at the bottem of the screen goes half way or it doesn't process at all and it just stays like this until i have to click somewhere where the screen just turns gray with not responding error or i must go to task manager to end the Corel process.

My computer system is Windows 7 Ultimate

Any suggestions?
