hi ulrike,
there really is no need to get disappointed with the rockettheme support. nanci responded to your other thread in less than 12 hours and to your 2nd post within minutes.
the support forum is available for current members, but at the same time i would like to point out the terms of service.
Support: RocketTheme offers these templates and designs ‘as is’, with no implied meaning that they will function exactly as you wish or with all 3rd party components and modules. Further, we offer no support via email or otherwise for installation, customization, administration, etc. A private members-only forum is available to Template Club members. RocketTheme does not commit to monitor these forums, but we reserve the right to respond and answer questions. You acknowledge by your use of the templates that it is at your sole risk, and that you assume full responsibility for all costs associated with all necessary servicing or repairs of any equipment you use in connection with the templates.
rokbox is a free rockettheme product but not part of a paid joomla template club membership.
still nanci was trying to help but did not get any further response from you.
sending out private messages (without being asked to do so) to moderators and especially team members might stay unanswered, just because of their work load.
in any case, we try to provide the best support we can, but please do accept that sometimes it is impossible to keep everybody happy.
all the best, kat
