Starting backup of labels error

Hi,

Promosyon

After successful backup of .eml files (about 1.2GB worth), I get the following...

Starting backup of labels
Network error occured, disconnected

Over and over again until it finally gives up. I've double checked my labels, there are no dashes, slashes, or anything but letters numbers and spaces

Help please!
