I have just purchased a design and it has slices already done but when it loads in to photoshop it says Slices are in the wrong format.

What are they talking about I don't no a lot about Photoshop just enough to get into trouble.

Any help on this problem?

The error says:

Could not read Adobe ImageReady specific data because the slices were in an unsupported format.

So what do we need to do here, I have never sliced anything before. The ones I most of the time are already sliced.

Are you opening the file in Photoshop or in ImageReady? And can you open the file at all?

I have it open in Photoshop and ImageReady just when you open ImageReady the error show up. If I no how to slice better I would try it my self.
