Font error when installing font on OSX 10.11.6

I have just installed abeat by kai font on my imac and and font book will not validate it - there is just the yellow triangle with an error message but I don’t know how to get the report on it. When I click on it in finder font file, it says it is installed but it doesn’t show up in any program where text is used. Can anybody help with this?

I have downloaded it several times from different places thinking it might be a problem with the source file but it is always the same.
