Cubasis/virtual Memory Problems Options

[musicteacher]

I am still having problems with Cubasis running on OS9.2. These problems appeared suddenly about two months ago to harass me. If I have virtual memory turned on (which the program says I'm not supposed to have turned on), I get a noticable latency on audio signal that I'm sending in through the external audio jack. Cubasis didn't used to have this latency. If I turn the virtual memory off like it says I should, any audio going in and any tracks I recorded before, even a long time ago, come out in short jagged bursts interspersed with silence.

Any advice or help would be greatly appreciated.
