I have had the same problem for years. After a few hours, Multiplicity, on my primary computer, shuts off & won't restart unless I uninstall and reinstall.
Today, I even upgraded to the latest version of your program (paid an additional $31) and THE SAME THING HAPPENED AGAIN only a few minutes ago.
I have done everything possible to avoid this problem. I have combed this forum for a solution. I download your bat & purge files. I tweaked my Avast anti-virus in every possible way. I shut off the anti-virus. I followed your always rather vague answers & minimalist solutions time & time again. And now, after I spent an additional $31, the same thing happened just a few minutes ago.
I don't want any more of your vague answers. I want a fix. Are you able to solve this for me? If not, I want my money back. I never have a problem with the secondary computer.
