Can't open .otf files

Hi, I’ve a problem with otf files of a certain font. Every time I try to open them I get a warning that they can’t be opened. However they work fine in fontexplorer and other programms. Any suggestions?

Thank you!

Could you send me the font?
What version of Glyphs do you have?

It’s version 1.2.23, I’ll send you the file. Thank you.
