Can you save as PDF from MathType instead of EPS? Make sure the font is installed on your system, or embedded inthe graphic, too.
We can distill eps file into PDF, it works in this case but when having more number of equations it is not possible to do any corrections in MathType because PDF file is an image file and it is not possible to edit in MathType.
@Peter, it's only the Mac version of MathType that can save as PDF. I suspect we'll build this capability into a future release of MathType for Windows, but OS X forced us to do it for the Mac.
@Ramprasad, I've got your EPS and I'll be running some tests with Euclid Symbol OTF with InDesign CC this morning. I'll report what I find.
