Naga no longer recognised in Synapse 2

I've got a Naga 2014, yes a little old perhaps... Anyway, it's been working fine but I went to make some new macro's the other day and saw that the device was not detected. I saw that there's a Synapse 3 but that does not appear to support the older mouse so to the support forums for me then... does anyone know of a fix for this, I saw there's a few posts but not actualy solution. Thanks
