The mistake people make with CrossEPG is that they enable too many functions. Keep it simple.
In your EPG settings menu, change the EPG storage location to a HDD or USB stick. Use one that is constantly attached.
Enter The CrossEPG menu, the first time you enter it, you have to save the default configs.
There is an urban myth that you should download the EPG at 4AM. If you want to automate it, pick whatever time suits you.
Go into OpenTV providers.
Highlight/enable Sky UK OpenTV then save
That is it. It will download the EPG data automatically at the time set.
As the time you selected is in the future, we can "download now" for the time being.
Do not get complicated by updating Rytec and the other providers. Ignore them. You can uninstall EPG importer if you are not gong to use it.
