this was originally an edit because it ocurred right after I posted, but since OP asks me not to edit, here's a reply.
I just rememberd miranda asked me to update, so I did and skypeweb gave me the error when I rebooted after that. I hadnt switched to alpha update channel after importing my old settings, changed update channels and now everything is fine. nevermind! sorry for the wasted space.
I suppose to make use of this post I will ask: I remember when skype cñassic plugin died, the current alternative used some capacity of the skype executable, I'm wondering if any of the p2p functions of supporting other's calls in skype are part of skypeweb?
