Error when posting embroidered products for sale

[MyDigiDesigns]

I get the above message when I try to post an embroidered hat or sweatshirt for sale. I've posted only two similar products, is there a limit to how many you can post? Any other reason why I can't sell these?

Shouldn't be a limit to the number of designs you can publish on Zazzle. 
I get this error sometimes, and I can't figure out why.
Maybe exit your design and try again in another few minutes?
