Hello +Nancy Best
I'm sorry that you're experiencing problems with doubleTwist.
Did you take a look at the sync guide? It contains steps for syncing along with some troubleshoot tips. Please let us know at which step you are encountering problems and what the error message is.
If after trying the troubleshooting steps, you are still seeing sync errors, please send us a debug package from your PC immediately after encountering the errors.
You can do this by holding down SHIFT while right-clicking on the doubleTwist icon in the System Tray and selecting "Send log files…".
Here's a short help page on how to send the debug package.http://www.doubletwist.com/help/question/doubletwist-sync-debug-mode/#E
