Try to decrease emulation level: open More tab of the action (1), check Emulation=>Custom (2) and set it to minimum.Ok almost done now stuck at setting value for a hidden field and it takes very long to complete this step and it's not setting value..
Then there is another submit form element. You should investigate captcha source code and find out which submit form is used on the website.
How did you manage to submit the form?Thanks for all the help i found a solution.
