I just installed Design Extender v1.0.7 and am experiencing erratic behavior from the Preset Manager when I click New. This is also dependent on which pull down menu option I have chosen as it either behaves unexpectedly or simply crashes DW. When I click Import I either receive the attached error or DW crashes.
I installed the latest extensions in the following order:
Design Extender 1.0.7
Data Bridge 1.0.2
DW CS6 / Mac OSX 10.7.4
