Just recently I have encountered error like this: http://img194.imageshack.us/img194/9002/wlwerroropen.png once I tried opening the posts/edit the previous post.
Before trying to reinstall, I'd love to hear if this can be solved :) www.adultloo.info
I read that you have Windows Live Writer Beta, i assume that is not the newest version of this product (14.0.8089.726). Do you open this form your local hard drive or form your blog engine (it is blog on Live Spaces?)?
