Memory error using movies under 1.82.01

Thanks Jon!

Just one more question - since I am using a older version than 1.83 (which is when MovieStim3 was added. That’s why I couldn’t find its demo) -
Is it possible to add any libraries/files to 1.82.01 version (I understand the library is moviepy) so that I can use MovieStim3 with 1.82.01?

I have a problem migrating to a later version. I did try version 1.84 but my Cedrus box was not working there.

Thank you very much !
