I hope there is someone who can answer this question! ---

Hi, Unfortunately, we no longer support 2.00 releases of FMOD. Please update to 2.01 or 2.02 and see whether the issue still occurs - if it does, feel free to let me know and I can investigate in further detail. If updating isn’t possible, I would still recommend updating to the latest version of the 2.00 release, 2.00.22.
