Take a look at this thread or just search the forum for "ai2mpc". There is a free program out there that can convert Adobe Illustrator v. 8 files to mpc files. If you can convert your files .ai & .eps files to dxf than you could also use LHR's dfx importer. I typically recommend trying the free stuff first and if that doesnt meet your expectations than open your wallet for the paid programs. As far as the fonts things goes, I didnt look at the site you mentioned, but if the fonts (typeface is more correct) are a TTF you should have no problem using them. Many of us have noticed that after your install a ttf in windows, for some reason, you generally have to exit and restart designer to get it to show up.
