Do you have access to a PC with Windows 7? Obsidian and any Windows from Win 8 to Win 10 have some issues within their communication, so this may cause all the messages and inconsistent memory handling. It is possible that a PC with Win 7 can be helpful to get the memory formatted and the sound fonts loaded correctly.
Very important: Attempt changes ONLY when you have fresh and fully charged batteries! I'm sure you had them, but I always remind members of this
Flash on Clash can be activated by checking the box within the Obsidian sound board tab that says "Enable Flash-On-Clash light effects".
Let me know if that worked, please. If not, I'll try to find another solution.
