Then I installed 1.6 in it's own folder with a different name (LDCad_1.6B2). This automatically generates a different folder under %appdata%.
I have copied over main.cfg from the 1.5 installation into 1.6, overwriting the existing file there. This results in having to accept the conditions of the software again. It did not ask me to locate the LDraw library or choose whether to use the zipped file (which I did the first time round). After that I see the empty interface for a split second, and then the screen goes black again.
Did you use the final 1.5 or one of its beta's ?
The only rendering related change in 1.6 is the default enabling of MSAA, but 1.5 had this option too so unless you were using the previous beta without it it won't use the default setting.
In the 1.6 main.cfg try changing the "aaKind" line into
aaKind=none
