Ok, I just ran into the problem that CoolTVGuide immediately shut itself down upon opening. Since the upgrade isn't available via the regular application catalog I decided to google around a bit and it appears the plugin "kills" itself from Februari the 1st 2017, which I've found out the hard way. (today after ignoring the update popup for months )
Anyways, since 7.3 was working fine for me I found that editing the plugin.py file at line 74 did the trick. (credits: BigBlack66 @ https://www.boxpirat...dbceb4e0de57815 ).
eolvs = '81201727584562'
change it to
eolvs = '81209927584562'
Or change it to whatever year you like. Otherwise you can just use the plugin.py attached.
So for anyone concerning the same issue copy the attached plugin.py to /Root/usr/lib/enigma2/python/Plugins/Extensions/CoolTVGuide, delete plugin.pyo (or rename to plugin.pyo.bak just in case), reboot enigma and it is working again till Februari 2099 without the update alert.
