i downloaded the trial, prepared to pay for the application if it appeared to be well supported, stable, and to have worthwhile new functionality; so far not so good, but this will be a good test of the "well supported" aspect

for now, i do not recommend this software; here's my bug report to Linotype; i will add a comment with the reply:

the promised upward compatibility seems to have failed; is there any way to recover from this?

i am on Mac OS X 10.4.11 on an MacBook Pro Core2Duo

i have been using FontExplorerX (1.2.3) for some time, and had quite a few sets defined

i installed the trial of Font ExplorerX Pro by copying the application to my hard drive, quitting all other apps, quitting FontExplorerX (1.2.3), and launching FontExplorerX Pro

at this point, i was pleased to see that all my sets and activation statuses were preserved

next i removed FontExplorerX items from System Prefs/Account/Login Items (assuming these were for version 1.2.3) and opened the prefs for FontExplorerX Pro; i noted that the preference was already set to launch at startup; i had to toggle this preference off and back on to get the FontExplorerX Pro item to appear in my Login Items

then i restarted my computer; when restart was complete, i looked in FontExplorerX Pro and observed that all of my sets were completely gone; the "SETS" item in the left pane has a disclosure triangle to its left, however toggling it does not disclose anything; this is a very big problem for me
