I can't find either of the files ("styles/custom.css" and "styles/admin.css") mentioned in the upgrade notes in the "ubbthreads-7-5-7\install\styles\" directory. I only have "1.txt", "2.txt", "3.txt", "4.txt", "5.txt" in mine.

As a result, I've aborted the upgrade and reverted back to the previous version. Did anyone else find this to be the case? Are these files supposed to be generated as a result of the upgrade?
