Artisteer upload theme problem

This pops up after I activate:

Directory has no index file.
Browsing this site or directory without an index file is prohibited.

If you are the site’s webmaster, you can remedy this problem by creating a default HTML page with one of the following names:

* index.html
* index.htm
* default.htm
* Default.htm
* home.html
* Home.chtml

NOTE: Filenames are case sensitive, i.e., Home.html is not the same as home.html

I have contunully tried to upload– Artisteer support says I may have used jooml or droopla export in error – no i chose wordpress theme to export continually with no lick – same issue opos up when I activate & go to visit theme. i tried to place an index. html – my husband created an index.html in his adobegolive program and he sent it to me but it comes up as document with my browser name – not an html document and i do not know where to add it in filezilla- tried to place it in themes but it did not work and i do not even know if it is in correct document form to upload anyway – that request is over my head.

Can anyone help?
My husband is rewording the request to send to artisteer support but I thought i would ask here- https://www.bettyboopdreams.com
