To start, your screw seems either stripped, or it was screwed on too far and now is stuck under (inside) the hilt. If the latter is the case, you have to punch it further into the blade to remove the blade. Photos would help.
As for your Diamond Controller freezing up, have you edited the font you are using? Does it happen on all/any font, or just the one?
I think I got the Screw in too far as it will not turn either direction. I thought my blade was too loose and the shock of blades clashing was causing the sound issue. As for the sound issue, I have never edited my sound fonts. Everything was default as it was sent to me. I really liked my Obsidian sound with Banes Heart. I got ahold of someone from Ultra Sabers to get a Repair Order started. They should already have my Saber. Thankfully it hasn't been too long since I purchased my Saber so hopefully most of the repairs needed will be covered. I guess I will find out. Unfortunately I do not have the tools here to fix my saber. I have a Drill but no small Drill bits. I would be afraid of stripping the threads on the side of my hilt too.
Thank you for replying, it seems this part of the forum is dead. So I really do appreciate you taking the time.
