My MediaDex 2.0 doesn't work proprely on MacOS X.5.5 ! I used it without problems on MacOS X.5.0 but, since I have updated the system it doesn't work anymore. No problem with installation and registration (MediaDex Pro) but, when I create a new Catalog I cannot open it. I can add assets but if I close the Catalog it's impossible to re-open it (Mediadex crashes, please see picture with the beginning of the crash log, see also my configuration). My X.5.5 system is a fresh install and I have no problems with other softwares installed. Beeing an User or an Administrator doesn't solve the problem. So, what's wrong ? Thank you for your Answer.
