Hi,

Do you have more than 1 instances of Studio opened or any other audio software that uses ASIO as device driver opened?

After examining the log, it appears the driver is set to have a buffer size of 128 samples. For ASIO usage, Studio requires a minimum of 1024 samples. Depending on your ASIO driver, there should be a setting you can alter to increase the sample buffer size. Alternatively, we recommend using the ASIO4ALL driver which is what we use for testing here at Firelight.
