He had already talked about this in November 2016, since then appeared the request to update the author's website, has since died.
However the plugin continued to function, had been posted a partial solution that simply was no longer bring up the required window upgrade-
Unfortunately from 1 February 2017 the plugin stopped working, I looked at the files in pyton the plugin in question, looking for a possible connection with this date, in fact, the line 74 is associated with a variable:
eolvs = '81201727584562'
is easy see the date in question, to run again the plugin simply put an early date, I would say that 2099 is just fine.
Then it is changed as well:
eolvs = '81209927584562'
Save the file and restart the GUI and you're done, CoolTVguide return to live again, but unfortunately can not do its author.
The file to edit plugin.py is in \ usr \ lib \ enigma2 \ python \ Plugins \ Extensions \ CoolTVG uid
Obviously you need to use an editor like UltraEdit or Notepad ++
Add in two stamp that explain where is the line to be changed, I hope to have made happy those who use CoolTvGuide and that with this fix it will still work fine.
