Hi Everett,
Most probably you are using DEMO version of the product. DEMO version don't have LicenseKey Property.
Please remove reference to wodFtpDLX.NET from your project, close VS.
Delete bin and obj folders. Uninstall wodFtpDLX.NET. Make sure it doesn't have any leftover DLLs (search your hard drive for WeOnlyDo.Client.FTP.dll and delete them).
Make sure it's not in the GAC anymore and if you find it there, uninstall it too.
Here is example how to search GAC for Weonlydo.Client.FTP instance.
---------------------------------
gacutil -l
---------------------------------
Here is example how to remove it from GAC:
---------------------------------
gacutil -u WeOnlyDo.Client.FTP
---------------------------------
Please download licensed version here:

This is automated process. Make sure you use same email address that is registered with our system, one you used when you have purchased the product.
When you're sure wodFtpDLX.NET is not installed anymore, now install it again, but make sure you install licensed version (one that asks for license key during installation).
Open VS, add reference back, and now try it.
This is longest way to make it work, but usually does work.
Let us know how it goes.
Regards,
Drazen
