Small 'bug', maybe too trivial to bother with. Seems to be a problem in the v2.5 installer associating .lgp files with the llb .exe. Or maybe it removed the association when I removed v2.
Did you un-install v.2.0 after installing v.2.5? Which version/release date does the designer have?
I uninstalled v2.0 first.
The version I installed was 28th Aug.
