Some options state that it doesn't support that type of file.
I've clicked on every one of the "open with" options. When I tried to download these from Design Pro, it showed up on my desktop as an. Geo's rep told me I could use either template for Avery 5371 or 8371. When I tried replacing my info with the preprinted info, using the same size fonts I used with PG, my info went WAY beyond the borders. The only BC templates I can find in Word (teacher, etc) have only 8 cards per page, but Geo's have 10. I've been using Printmaster Gold (PG) but, of course, that's not available for Macs. All I want to do is print my own business cards (BC) onto the same Geographic's "Cloud" cards I've been using for more than 10 years. My apologies if this sounds too simple, but I'm so frustrated that I'm about to toss this new G5 in the trash.
