Firetv Gen1 Help req with Kodi Starting with black screen..

Hi chaps,

Recently I had a black screen when trying to start kodi, (15.2) … all I could do was to press the home key on the remote and force close.
I tried again, and I was greeted with the same black screen.

After doing some digging around I found out that it may well be the cache that had grown to large…. and that the only way to get kodi to run again was to delete the cache.

well I did this, and kodi did run again,.. but it was like a brand new install…. all of my settings had been removed as well.
Obviously I don’t relish the idea of having to go through the procedure of having to reset all of my old settings including having to re-add all of my movies/tv/music from my nas again.

Is there a way of being able to control this cache, or other settings (that I could clean on a by monthly basis) so that i wont have to suffer the panic of seeing another black screen.

It’s a stock firetv gen 1 box… with only addons from kodis repo. addons are iplayer, youtube, and ariel atv4 screensaver.
(I’m not interested in any other addons as I am an amazon subscriber, and I don’t trust other addons).

(strange thing is, my 16gig ipad2 running 15.2 (that has hardly any memory left,) still runs like a dream).

any guidance would be much appreciated…
