DDR X2 Theme Crash [SM5 Beta 3]

I'm using a DDR X2 theme on Stepmania 5 Beta 3 and I keep getting an error whenever I try to go into the options menu before a song.

Parse error in "ScreenOptionsMaster::Remove".

This never happened on Beta 2 (I used the same theme on Beta 2.)
Help me out!

Report it to the theme author and tell them to fix it and update their theme.
If the theme author doesn't know how to fix it, they can come here or to the IRC channel (#stepmania-devs on irc.freenode.net) to ask for help.
If the theme is abandoned by the author, post a download link for it and maybe someone will be willing to dig into it and figure out what's wrong.

(though from what I saw in the "preview4e2(169)" release, the X2 theme is a mess of copy paste and commented code and probably spews more errors than can be fixed in reasonable time)

I think it might be abandoned, considering it doesn't look like the author updated it in over 2 years.
