I'm experiencing hanging at "Downloading individual programme schedules" too only since a few weeks ago.
It occurred after upgrading my Vu+ Duo2 to the latest build of OpenATV 6.4, so I flashed a vanilla image of 6.3 to no avail.
I've tried changing all options within the plugin too (No. of days, use provided lamedb, different regions, etc), which hasn't helped.
I've also tried my own compilation of the IPK file as well as the one on this forum, both being v1.14. I've noticed it isn't available to download via Plugins too.
Please help ASAP, Kiddac. EPG Importer and Cross EPG are nothing compared to your solution!
