Memory error when running Hiduino and Pro Tools

I have my MEGA2560 configured for Hiduino, and was able to compile it with it's own name. The Hiduino bootloaded Arduino shows up under Devices, and is able to be selected in Pro Tools, and any other software I decide to connect it to.

Right now, Hiduino is not being routed to any software. I can open MIDI-OX or Bome MIDI Translator and route Hiduino in those programs successfully. However, if Pro Tools is open first, I cannot connect Hiduino to MIDI-OX or Bome and receive this error;

"Hiduino: There is not enough memory available for this task. Quit one or more applications to increase available memory, and then try again."

Also, If i connect Hiduino in MIDI-OX or Bome before opening Pro Tools, Pro Tools will not load and crashes (because there isn't enough memory to load??).

I have 64gb of memory in the CPU, more than enough. Pro Tools is using 558,144k of memory. Kind of stumped why this is happening.

I only have this audio recording program, and curious if its only with Pro Tools, or other programs as well. Hopefully someone else out there could help troubleshoot with me.
