Oh no!!!
Seems to be the tale of the Titanic..... sank in its maiden voyage!
I'd do the following:
Download Version 526 from http://www.macecraft.com/downloads/jv16pt_setup_hb.exe
Get your license and have it near.
Unstall everything you have. After that, go to the install dir and delete the install dir too( should have the lic file on it..., but delete that too).
Now install ( clean install).
Once finished, no not click on the last page of the installer ( Start JV16...). Wait.
get the lic file and paste it inside the install dir
Now press finish
Program should start its firsrt run already registered.
If not, them jouni.flemming@macecraft.com
Cheers!
