Draftsight 2018 SP1 crashes when i try to print

Hi everyone. I was waiting for some help in the "iquestions" section wich i can't find anymore... I try again here.

I'm using draftsight from years. I recently upgradet it from 2016 version to 2018 sp1 version on my win10 pro 64-bit 8 Gbite RAM computer. I usually use a free licence because i don't need extra features for my job, actually. The program run properly but crashes every time i try to print any kind of file (even the empty noname0). I do non think it's a printer or driver problem because i haven't even had the opportunity to choose the printer. It crashes also with "print configuration" command. I tryed to activate the trial professional licence after a complete uninstall and a new installation (launching the installation file as administrator). Nothing has changed and i can't guess anything else to fix the problem. Can anyone help me? I'm still using draftsight and using a different cad to print my drawing for now, but it's a mess and a waste of time.

Thanks in advance, Gianluca
