A friend of mine tried to add some categories and products via the "CVS upload". It gets to about 14 products and stops. Everything else has to be added manually or else we get nothing but errors. Is this a demo limitation?

i know the demo is limited to how many products and categories you can have...
 
I have enterprise version and the cvs works fine

Does that mean there is a demo limitation on the CVS? According to the information on the demo, it should handle about 50 entries or so, correct? So why would it only allow 14 products and one(+ one sub) category? Hmmm...

This could be a factor... in the trial version most of the category limit is used up by "article" categories if you loaded the sample data. I found when I deleted most of the news categories that I could then add new product categories.
