Hi Andrew.,
I had removed the _badwolf.STY & .STX files from the BIAB Styles Folder yesterday and then followed up by downloading the ExtraPak 2 installer from my PG account files.

I re-installed Xtrapak2 and re-booted the computer with the same end result (_badwolf.STY freezing on pressing play).
All other files and styles still work fine EXCEPT _badwolf.

I'm thinking maybe un-install and full new re-install of BIAB with all extras and PAKs may be the only other option.??
Do you have a recommended step-by-step method of doing that?

Thanks,
Gary.
