I see it on there now, so i'll proceed with my advice: It should open your save location by default, but on the off chance it does not, you can find it under the Steam installation folder, where the cloud sync data is: Steam\userdata\<userid>\55230\remote
Implementation details: To find the save location, the program uses a stupid reflection hack to access an internal Java class that can read the registry, to avoid having to ship any extra DLL's. I believe it works on all current versions of Java 7, but it will probably break some day. Next version, i should probably add some error output so that i can see under what circumstances it doesn't do its job. (For those who are afraid of the word "hack", i mean it's a shoddy job, not in the sense of stealing your credit cards.)
