omg u are all nabs!!!! I have two versions and xfire detect both. Solution is so fucking easy.
Install Swat 4 1.1, then instal Swat 4 1.0 somewhere else.
Then change name of folder "content" from 1.1 ver to ex. content11.
Then take folder "content" from 1.0 verion and copy it to the same folder where u have content11.
Now xfire detects 1.0 version, when u change name of folder content to ex. content10 and content11 to content xfire will detect 1.1 ver. If u are too nab to understand it ill make a pics of my folders and post it here. But ill do it later when be at home.
