Thank you for the mail. I was able to log in.
There is something wrong with your joomla installation! Did you try to install any other component on your website? It doesn't work. I tried components, plugins and modules. Adminpraise, admintools, cb - neither of them could install there.
My suggestion here would be - try to install an extension. If you find an extension that installs on your website and it is just hotspots that is not able to install, then I'll jump and spend days if necessary, but you'll get it installed!
Right now I see that the problem is not related to hotspots in any way so I don't want to spend time with.
Cheers,
Daniel
P.S. As I said - find a way to install another extension on your website - if you manage to do it, I'll be happy to make hotspots work for you!
