Hi Paul,
it's StasPraha :)
yes I am refering to VE PRO 6. I am using more or less the same project for more than one year without any problems (except that sometimes if I left it over the night it "forgets" VI PRO samples and I had to restart it).
Right after I installed Mojave on both computer (Mac Book Pro 2018, 32 GB RAM iMac) it started to behave as I described.
I'm sending you DiagnosticReports to address you mentioned
thanks and best regards
Stan
