Corel Draw x6 and Artcam Pro / EPS Problem

Hello dear friends, I bought Corel Draw x6. Everythings good. But there is a problem about EPS files.

We uses CNC machine and so we uses Artcam Pro 2008.

Firstly we design a project file in Corel X4 and export EPS. Then we open it in Artcam Pro 2008. There is no error and issues. But we export same project in Corel X6 to Artcam Pro 2008, there is many postscript error. Artcam says "Ignore All" , and when i clicked Ignore All button, the project file appears empty.

We tried that suggestions but there is still same problem : http://coreldraw.com/forums/p/21950/97718.aspx

How can we fix that?

Thanks
