If you start CuteFTP Pro and Offline is always in the title bar, and the Transfer Engine icon does not appear in the system tray, CuteFTP Pro and the Transfer Engine have become disassociated.
Close CuteFTP Pro.
On your desktop, double-click the My Computer icon.
Navigate to the folder where you installed the Transfer Engine. The default location is C:\Program Files\GlobalSCAPE\CuteFTP Pro\TE\.
Double-click ftpte.exe. This will start the Transfer Engine.
Start CuteFTP Pro. The two programs should now be associated again.
If you still get the same error, then it may be necessary to re-install the software. You can download the latest version of CuteFTP Pro 3 from here http://www.globalscape.com/files/cuteftppro.exe or from here ftp://ftp.cuteftp.com/pub/cuteftppro/cuteftppro.exe. After downloading, run the installation and choose the REPAIR option. This should correct the problem.
