If these are new errors consider the possibility that they may be related to the recent integration of the Chrome browser with the ability to access remote MIDI servers. Apparently the insufficient memory error is showing up when other applications are in conflict for the MIDI driver, and most people are not aware that Chrome, or more accurately sites to which it connects, may be hijacking the driver. If you are not using chrome then look for another conflicting application. If you have chrome, try:
1. In chrome navigate to 'Settings > Advanced Settings > Content Settings'.
2. Locate the 'MIDI devices full control' section.
3. Enable the 'Do not allow any sites to use system exclusive messages to access MIDI devices' option.
