tanster on "[Plugin: W3 Total Cache] 0.9.2.11 won't use existing MaxCDN pullzone"

I am in the exact same situation, WordPress installed in root.

I can't choose the zone I already created in MaxCDN, but if I click the "Create pull zone" button on the WTC CDN tab, I get the "Something is wrong: You have reached the limit of zones you can create" error.

Did any of you resolve this issue?

I am using WordPress 3.5.2 and W3 Total Cache 0.9.2.11.

Any advice is greatly appreciated!

Thanks,
tanster
