[LDCad] red "X" instead of lego bricks

[jas kapela]

Glad it worked, 

just for future reference re-installing LDCad will NOT reset its configuration unless you install it under a different main folder name

oh, didin't know that. But was helpful that during re-installation, it asked for the library location and after I specify it - it works.
Before, even I changed pref in LDCat- it didn't connect to the library.
