Hey,
first, please look at the rules and acknowledge them before your next post
Then, your questions:
1) You can either download the entire package from the Ultrasabers website or try the "Save" function in the "Write Sounds" section. Just be sure to select the bank whose font you want to save.
2) When you change the volume, you have to re-write the fonts. If you didn't change them, then this will only decrease the volume but not the font.
