fyi: i reverted to previous sdk (4333796). that seemed to get me back working. (that and re-installing the add'l resources and all the mavens...) but i figured it was the latest sdk that was the cause. thanks.
go to the main b4x page and use the new link for downloading the sdk. erel put it up yesterday (refers to 4333796 in the url). i happened to have kept mine from before. i'm looking for erel's post from yesterday.
