Sorry for the slow response. We are not sure about the problem. Please email us more detailed info about your backup tasks; also try to manually start the backup task and see how it goes.
To pin-point the problem, it is better if you can open the Progress Dialog so that you can tell what the software is doing: which file it is uploading and the detailed error message. Sometimes, the problem can be caused by a corrupted file on your local disk.
Whenever you see any upload problem, please double check your Internet connection, make sure you can logon www.drivehq.com using Internet Explorer. Also try to upload the file using DriveHQ FileManager client software and see if it works. If you still have problems, please email us the detailed info and a screenshot of the problem.
FYI, we are launching a new version "Cloud Storage & Cloud IT Solution 5.0" system. Once launched, you can try the new version Online Backup 5.0. We expect the new version will be launched very soon. (within 2 weeks).
