It can happen on older versions of FreeRIP Pro that ripping stops at 0%.
In this case go in FreeRIP options window (File->Settings->Options... menu) and set "CD sectors per read" to 16.
"CD sectors per read" parameter controls how many sectors the CD drive should read for each reading operation. Safest value is 16 which is compatible with all the CD drive, but many drives allow higher values, but in the case your drive does not support a higher value FreeRIP can stop working (track ripping progress stays on 0% and never increase).
If you like you can try a higher value and see which is the highest your CD drive supports.
