It does not let me to log into my Rendo account from the Purchases tab. It never has. Not once. I gives me the login screen over and over again. I even rest my password just to be sure. I always used the 'Install from ZIP' option or manually moved files and never once have I encountered anything asking for a validation like this. I find it a bit offputting and strange. After the first fiasco, I hope you understand why I'm a bit, just a little bit,...miffed.
