W10 did a clean up using Reimage and when re-booting I think windows v 1803 took place. The end result was a mess and the most important factor was that I lost my email. When I selected TB it acted like I was starting from square zero. I discovered that the folder AppData was missing which of course meant that my profile was missing. However, my back up program had created a file which contains the whole TB thread. I can't use my b/u program which is an unrelated problem. But, how do I use the AppData folder that was created? Thanks
