We could not find any issues on our end. Please compress (zip) the gedcom file and email it to us. We will try to upload it and try to replicate the problem.
TPS Being tired to wait when you will update my sites with the zip files I have send you, I tried to upload not from Mac, as I always did it, but through Windows (from my mac with VMware Fusion) and the ged files where accepted !!
So have a look at your system why geds from Mac are not.
