E-Tools & Presteige Class

[Balfin]

I've got a patched version of E-tools, and I downloaded a bunch of presteige classes, but the bladesinger class I found was the one from Tome and Blood, not the updated one in the web enhancment. Does anyone know if there is an e-tools version of this out there? I tried making my own with the e-tools helper, but it keeps crashing.

Thanks.
