trouble loggin in to wpmudev premium

Hi there,
Whenever I log onto WPMUDEV something goes a little bit wrong. After filling out my username and PW, I;m redireded to https://premium.wpmudev.org/wp-admin/profile.php#show2AuthActivator where it says I do not have access....If I then go to another page within wpmudev it turns out I'm logged in after alll....Not a biggie, but it's a little annoying (to be totally honest...) Is there something I'm doing wrong?
Looking forward to hearing from you! thanks, Joost
