I'm pretty sure there is no "issue"; Lightroom 4.4 cannot import these RAW files but you can convert them to DNG and then the DNG files can be imported into Lightroom 4.4.
Or were you referring to some other issue? (this wasn't really clear)
Hi Kenneth L,
Please use the below link to convert your raw files to DNG files then you would be able to import the files in Lightroom 4.4
