It's worth mentioning that these are files that the anti-aliasing worked fine with in my previous version. I generally have problems with CYMK colour, but that's a different story.
When I open the file there is no anti aliasing at all, each pixel is rendered 100% opaque which makes for some very jagged logos and leaves them unworkable for me.

This is what the image should look like -^

-^ This is what it looks like opened as a .EPS with the anti-alias option ticked. Interestingly if I untick the anti-alias option the file doesn't open at all.
I'm not sure what the problem is here and there are very few options to change, but there is clearly something not working the way it should.
Can anyone advise please?
Thanks in advance.
