After you open LW, let it settle. Don't do anything. Leave it for over 30 mins. Then go back & see how it is. Is the connection quality ok then?

You share a lot of files & probably have lots of incomplete files which can take a considerable time to load. Doing anything with LW before its finished loading & accounting for them as well as trying to establish a connection with each incomplete, can give LW a few problems with connection quality, etc.

Particularly if you resume all your files. This can have a dramatic effect of LW's connection quality & use up all of LW's resources.
