Thanks for your reply! I used to use Erminig (the current version, I believe) but it had trouble with shifting time zones on Google (events showed up an hour off, occasionally) and with odd repeating rules that worked on Google. I really liked syncing with Erminig but occasionally lost data due to the above issues. So, since then, I use GPE as an offline viewer for my calendar, rather than a place to enter new events, and just subscribe to my GCal. However, that recently stopped working too, due to the error I mentioned in the previous post. Anyone else experience that error?
