I've scoured Google before coming here. (I've send a ticket to steam)

I'm wondering if anyone else has encountered this issue before, and if so, what you did to resolve it.

When I try to enter the verification code they send me, it pops up saying "Email code you entered was incorrect"

Any help would be much appreciated!

Get a new code and then copy & paste it.

Seems like a question better suited for the Steam forums. Just make a new account and ask there.
