When I click on the Blackboard link in GTC4me, I get an error page. What do I do now? The first time you access Blackboard through GTC4me, you will have to enter your credentials to create a trusted link. Click on the "Enter My Credentials" link and enter your GTC4me username (without using "gts\") and password. If you are getting an error that does not have the "Enter My Credentials" link, contact Tech Fix at (864) 250-8000.
