CrossEPG 0.6.2 unable to update rytec providers

[p17blo]

Under CrossEPG 0.6.2 selecting Update Rytec Providers results in an error
"Cannot retrieve rytec sources"
Having researched this a lot, i've already tried some of the reported updates for this, but none of those have worked.
If CrossEPG creates any logs files, please advise the location and I will upload these

Note:- I am unable to upgrade to 0.8.1 as that does not work on my OS - I have raised a separate issue for that error
