Sorry all, but this is a last minute rush to get something out for testing some of the issues reported.
Please refer to the Source Code tab for details of work done, but to summarise:
An issue with threading has been addressed.
Some reverse-engineering of mc_com.exe has been undertaken, and is up for some beta-testing! ;-)
An enhancement to allow the user to save the selected fanart to disk (thanks Ian).
Hopefully, multi-episode TV shows are working properly (sorry, I should have checked it!).
Had a quick look before, and it looks like the TV Shows list is working again, including some work towards missing episodes.
So try them out, and let us know about any new issues!
Ensure you have .NET4.0 installed (http://www.microsoft.com/download/en/details.aspx?id=17718)
Do a clean install, i.e. delete all existing files except Settings folder, OR copy Settings folder to new install directory.
A big thanks to the recently volunteered developers, and especially the users who have contributed some code and bug-fixes - much appreciated, guys!
