I have done quite a progress creating my blog. At some point in the process I forgot my password and reset it. After doing so, when I log on to my Dashboard all the changes made have disappeared. My library is empty, my pages no longer there, My Blog has been reseted to My Blog... just a template blog with a default theme, instead of the one I had purchased and loaded. I only have the one blog, so there's no confusion in terms of having created/deleted the original one.
Anything helps. This is nerve wrecking.
