When you get the chance, give me the official title of the rotation you're trying to download. I'll try to download that exact one too.
I just tried downloading one of my own from 2008, and at first it didn't show up for me either. I think when I changed the year, I didn't hit the "Change Date" button once I was done. I just went to "Save and Exit."
When I tried a second time, after changing the year to 2010, I made sure I hit "Change Date", THEN I went to "Save and Exit." This time, it showed up in my calendar.
I'm going to try that again and see if that might be the problem. I'll be back...
** Yep, that was definitely my problem. For whatever reason, I didn't hit "Change Date," and the rotation didn't show up. I tried it with two forum members' rotations and a Cathe rotation. Perhaps you skipped this step too?
