ok I've read the last two pages. I never used yappari before and decided to install it yesterday. Bad timing it seems... So does this 404 error means that
1- for now it's totally unusuable
or 2- is it usuable if you already have contacts in yappari?

If 1: ok let's wait and hope for an update
2: Then is there a way to manually add contacts to yappari? (I have none since I installed it only yesterday and there is this syncro failure)
