Did you use the latest beta r174?
If yes, and you're still having issues, then maybe try a silly default template extract, just to see if it works.
After that, maybe give Tom a shout, see what he says.
read carefully the problem i have! the problem is not from construct 2 release version and yes i use the latest r174 or whatever is it! the problem is when it tryes to connect to this here scirra.com/arcade/upload when i try by forum or construct 2 to get to that page i get the error above! but this happens only on this account! gamecorptm! i have another account called gamecorpstudio its fresh new! on that one everything works perfect!
