I get an error message for trying to add add-ons and syncing in anki 2.0. I recently uninstalled 2.1 since it kept crashing after I used image occlusion add-on. Before I uninstalled I downgraded and quit. Now I re-installed 2.0 but I can’t seem to add any add-ons without error codes! I synced my 2.1 deck before I uninstalled so when I redownloaded anki my decks are still there but I can’t sync and I can’t use any of my add-ons properly. Please help!
