Help! All my accounts are getting logged out as soon as I log in

[AngelicaFlower]

I'm getting error messages in all of our accounts on this computer. It says "Cannot start http server for devtools."  "Unable to move cache." and "Unable to create cache." Help! What do I do?

I've tried different versions of Firestorm and SL on a Windows 10 computer. 

Thanks.

if you haven't already try logging in to a different region from the one you last logged out from

This one is really strange - I get most search results it in relation to chromium / Android installation.

Could you ever login without problems on your computer? Did you recently install any update / made changes?
