Hello, Ali! Thank you for your fast reply.  One thread is as follows: Arcia'S Temple > Arcia 's Babylon > Dangereuse (the selected Sim).  I can read everything about the Sim, see the pictures, can click to the several links for neccessary stuff, but I can't download the selected Sim, because there is no Download-link at the bottom of the description.  That's frustrating. According to the following comments of other users it must have been downloadable.

It's the same with many other Sims of this section.

Yesterday I wanted to get some of Acia's Sims.  Some were available (to be downloaded), but the very most of them have no download-sign.

How can I get the sownloads?  I would be very thankful for your help!
