Just noticed that with time, grabbing channels every day, some channels of the same provider started having the problem :
[Error ] Unable to update channel Animal Planet
[Critical] See log file for details
[Critical] Exception.Message: Object reference not set to an instance of an object
[Critical] Exception.StackTrace: at WGconsole.Program.UpdateChannel (System.String strIndex, WGconsole.ChannelToUpdate Chan, WGconsole.XmlTarget xTarget) [0x00e4d] in <7fc5d76979374a05ad2db534f70a5f2a>:0
at WGconsole.Program.ConsoleApplication (System.String[] args) [0x015e6] in <7fc5d76979374a05ad2db534f70a5f2a>:0
[ Info ] Existing guide data restored!
The next day the same channel was grabbed again with errors. So I tried "force" using the same guide.xml and all critical errors disappeared !! Could it be that incremental mode somehow formats strings incorrectly and cannot be readed again by webgrab ? Is it possible that the problem is due to new version of .NET ?
Had the same issue as matt8861, and can confirm changing to force update fixes the issue
Developers hopefully are working on. We have to wait.
