Hi Paul,
thank You for this advice, I will describe my problem in mail to your engineers. On Monday ofc.

Best regards Sinuhe.

Thank You Paride, for Your care. Do You really think I should write directly and private to Paul? Something was changed for last years I see.
I found temporary solution:

1/ By accident I found plug-in version 3.3.3.76 on my HDD - I installed it
2/ I checked in Poser - everything is ok, no any ...

Thank You for the advice and next stupid question: who (where) is poser plug-in developer? I was sure this is a good place for my problem.
Best regards - Sinuhe

Hi Paride,
so, is something similar to this issue with another plug-in? By the way, it is absolutely incomprehensible for me, why plug-in after some period of inactivity wants to check its validation. I just can't understand this politic. Is this method to force to use Poser every day??? :lol ...

Of course, this is the first what I checked, however I didn't change anything with my software since autumn 2016 (new Poser version), better I even worked 10 days ago with both - Poser+plug-in and standalone version. Anyway all settings of my firewall are checked and are on for Octane and Poser.

Can someone help me with this drama?

Hi Paul, my honesty let me write finally some words :). You were right , I have no idea how it was happened, but it was vcard's problem. On Saturday I bought "anyname" GF GT660 and successfuly tried to render few scenes mainly with volumetric light. Everything is ok both: with standalone 1.55 and ...

Hi again. Just finished with my trials and changes. So, I underclocked my vcard according to Your suggestion. About 40 % down was stabilized the situation, however rendertime dramatically increased ab. 3-4 times, depending of used kernel. Moderate complex scene, which was rendered 3-4 hours in this ...

Hi Paul. Forgive me I muted for last days, however I really appreciate Your hints and advices :D .
1. I can't try another vcard, I am to poor ;) for this I would rather buy new computer than only card :)
2. I tried to check all other possibilities and what is my fault, I miss latest drivers update ...
