I have two computers, and I was working with this kind which troubles me a lot. I have files to the both, and while I was uploading this computer was troubling. The Windows Dropbox is neither responding nor retrieving files from web. I have important files on this computer and I want to send it to the other one, but not lucky for me since before doing it error interrupts. Internet connection is very active, and now I don't know why it sync nor even connects and re-links. Please help me.
