I reported this to Reason Studios as it could be a problem with the plugin. However, when I try the AU, I get a different problem where the screen isn't drawn correctly:The operation could not be completed because there are too many files open.
This could be because you are working with a self-contained song containing a very high number of external samples. Please visit the Support section at www.reasonstudios.com for more information and workarounds.
Any idea what is wrong?
