So, are you getting that in a message that pops up on the screen or actually within the browser window. Tube Toolbox embeds an Internet Explorer window into the program so if Google is telling you to turn your cookies on, you should be able to go into your general Internet Settings for your computer and turn cookies on.
If you are getting a pop up message that says "Google has given you the following error message:...." then it's an error that I've never seen before but we could probably get it worked out. If this is the case, let me know what username you are logging in with (you can email it to
support@TubeToolbox.com) and we'll test your account.
