I know this question may have been asked and answered, but I am new to the jailbreak/xmbc/icefilms deal.
I have gone through the process of installing everything necessary on my atv2 and had it working (watched 2 tv shows fine). Then last night around 9pm cst i tried to play an HD movie and was getting a cache full error. So I searched around forums and found out that I may need to clear the cache folder. Did that, and was getting "X - script.plugin.error" in the right hand corner. I was getting this either when I was attempting to view a folder or sometimes the file itself. I could not stream a video anymore.
After this i put the atv to sleep and went to watch good ole netflix...
This morning I turned on atv assuming it may be a problem with Icefilms, and there was a big meta update. I figured this patch may fix last nights issue. But, no, I am still getting the error. I am able to see folders sometimes but still can not get into the show or movie selection.
Steps I took last night --
Change out the default.py via FTP (PC - Windows7) (this didn't work)
clear cache via FTP (PC - Windows7) (this didn't work)
uninstall icefilms >> install icefilms (this didn't work)
