@hzd You’ve got the package installed at two different places somehow. Do you have Max for Live, by chance? I remember a little while back someone had the same problem as you, and it had something to do with Live copying Max externals around, or something.
Anyway, I’d recommend that you search your computer for all files named mira.frame.mxo. There may only be one folder named Mira, but there’s definitely an old version of the mira.frame.mxo file around somewhere. Find it and get rid of it.
