From the first moment I started using solidworks 
I had problems that were never solved by the team that sold me and dassaut. 
I'm going to make a short list of some of the problems that never get resolved.
I'm already tired of doing RX and not having a solution:

solids turn black;
assemblies turn invisible;
I could never save a simulation, the program closes(this is the worst of problems);
it takes more than 30 minutes to save some mounts;
just killed the toolbox, I can't put screws anymore;
ended the routing;
I have to save to the platform before exporting to my computer;
the old custom properties is over;
ask for password every 30 min;

I can spend hours talking about the problems I have
ps:it's not the computer's fault, i use a 32gb i9 with a gamer gpu
