I'm trying Adwords Editor and having troubles with 'Ad new Adwords account'. Getting [error number 4] message: Either account you are trying to access does not exist or you don't have permission to modify this account. Adwords account do exist, I can modify it online and I have administrative rights on this account. Email and password that I'm trying to enter is working for manual online entering Adwords site. And I tried this for a couple of times to make sure that my typing is correct. What could be wrong?
