Hi Jil and Tony,
I made some changes to your account and you should no longer have the "Resend Activation" message when logging into the EDU Site.
I tried it on my end and I was able to log in successfully. If you still have the same error, do reply back so I can look further into it.
We are currently looking into this error and we will update right away once resolved. In the meantime, while we are resolving this, please create and register for another account in the Education Community Site using a different email address.
Do update us if you still have the same error once you try to download T-Splines.
I'm having the same problem too. It was fin on the 29th of February 2013 and the 1st of March 2013. I'm still downloading 3DS MAX. However after I finished downloading TSplines I kept get the re-activation message. Any help would me appreciated thank you.
