[Urgent] Velo engine refuses to work for me now

[hobgoblinpie]

After finding a glitch with the frame offset function (I decided to see if half frames would work, and I assumed it would tell me they wouldn't), I am now unable to play any songs at all, as no arrows appear, the time bar is always full and no buttons work (besides the arrows). See video for details.

I would appreciate it if it could be fixed very soon, as I'm participating in a tournament, and I will not be able to do much with the laggy-as-hell legacy engine :P
