AdWords Editor is unable to check or post some of your changes.

I was trying to create some content network campaigns in Google AdWords editor today and this error message came up when I tried to post the changes:

"AdWords Editor is unable to check or post some of your changes, because doing so would cause you to exceed AdWords account limits. In order to
complete your request, please revert some of your unposted changes or delete some items, then retry your request. For more information about AdWords account limits, please contact AdWords Support.
(Error number: 17)"

Anyone has any idea what went wrong? This account has roughtly 40++ campaigns with 1900++ keywords.

Were you already approved for 40 campaigns? The limit is 25, unless you get it lifted.
