I picked this info up on the Creative Expresions website and thought I would pass it on:
"Important Notice: Using Creative Expressions Embossing Folders with the Grand Calibur
In order to achieve the outstanding depth of impression that they offer, our Embossing Folders are slightly thicker than competitor products. As a result the Folders cannot be put through your Spellbinders Grand Calibur using the standard sandwich combination. Attempting to put them through using the standard sandwich may result in damage to your Grand Calibur machine.
Spellbinders plan to release a new plate for the Grand Calibur early in the New Year to improve its compatibility with our Embossing Folders. However, in the meantime, to use the Folders with your Grand Calibur machine please use the sandwich combination below:
Grand Calibur Cutting Plate (C)
CE Embossing Folder and paper/card
Grand Calibur Tan Embossing Mat
Wizard S5 Die Spacer Plate (Part code: WIZW -017)
All other die cutting and embossing machines remain unaffected and are completely compatible with our Embossing Folders.

I will post the sandwich in the Glossary, so it doesn't get lost.
Please also note the sandwich for die cutting with the Provocraft/Cuttlebug dies (like those that are supplied with your machine), also need a different sandwich than the Spellbinder, Joy Craft, Miranne dies.
