The website is fully in German (but not realy a problem for me), the forum is deserted as the maker does rarely respond to mentioned problems of users. So, a total bummer for me. I'll have to switch to VM although it is way over-dimensioned for me.....
we can not understand what are you speaking about. Many Shops are allready installed and working fine. What was the problem? Friendly speaking it looks like an advertising for a competitive shop ... We hope that users test them self and are not affraid because of those feedback.
Hope you write what problems you had exact. Maybe you even send us a screenshot of your problem.
