Hi guys, thank you so so so much for replying. I really appreciate it. Here is one thing: When I open poser 11 (the trial version) it says 64-bit. Does that mean anything? My mac is a mac os 10.13.6 I installed the latest version from here: posersoftware

Here on renderosity I can check the poser-software site and ugrade for 99 dollars to poser 11. There i can click on "check eligibility" and on their site I can paste my serial number. When I do so, it tells me :

Your license key could not be validated because of: Invalid Poser License Key For assistance, please can contact Poser Support.

I legally purchased poser back in 2015, so I'm not sure what to do. I did write to support but of course this might take a while... Some of you mentioned that I could upgrade for free. Where can I find that? Is that an offer from the official site?

Still, it keeps crashing down. Even if I don't do anything... just moving the mouse cursor over the interface and it crashes down... :( :( :( This did happen with Poser 10, but only if I had big files or big cloth simmulation ... but now I can't use neither 10 nor 11 ...
