Has anyone run into a problem with newton on a newer computer using v15f: tried it last night on my new machine and it would not simulate: grabbed project from old machine and erase simulation data tried again nothing: might try to install v14 and try again tonight

Any update on your end John?
Is Newton working for you?

Maybe its something silly ,I kept crashing because I turned hair to 0 density and forgot to change it back and it crashed AM when trying to render ,Maybe its a simmular thing

No luck so far....I took same project into v14 and after notice created in new version it "newton " simulated fine. I v15 it does nothing ignores the request. Wonndering if I can do a clean install without needing a new key ?

Well found out in the chor there are a few selections of features related to the newton plugin that were all set to off. Set the first 2 to on and got simulation....weird this was not necessary in v14 when I reinstalled it from the cd or when I installed v15 on the old computer ..just glad I found the solution

Just make sure you backup the file master0.lic file from the V15 folder, just in case. However, taking a backup of that file is something you should do anyway
