This isn't a question for the VMTN Communities but for VMware Education as we cannot do anything about the situation for you.
Thanks for the helpful tips on how to post forum messages, but this is the Education forum. I read the other posts before asking here, and I'm asking here in the first place because I haven't received any replies from the contact info number on the mylearn site itself.
Since I'm probably not the only one having the issue, I figured it's either due to a current problem with the site, or that another student on the education forum might be familiar with the same problem.
I've spoken to a contact within VMware - they have suggested this course of action for you:
1. Logout of myLearn
2. Clear your browser cache and cookies
3. Log back in to myLearn and retry the registration
You could also try an alternate browser.
If the above doesn't work, their next advice would be to email myLearn_support@vmware.com - they can check the setup of your account on the system.
