unknown TException

I have tried to load the wavelab 6 program and it loads but when I attempt to use it I get this message “Unknown TException”, and I cannot access the program. Has anyone had this experience and what did you do to fix it?

Which Windows is that?
Sometimes, when the pc is on for a long time like a month, it starts giving such errors randomly on launch. I have a suspicion that that might somehow be related to GDI resources as around that time I start to have refresh problems of level meters in Samplitude / Sequoia too. So far haven’t found a cure to these issues but a restart.
