Hejhej!
Open the galaxy file with a text editor and check the "versionnumber" at the very top. It has to be 1 for the 1.05 patch. Since you used GalaxyForge 1.1 the map might not work at all. Either upgrade to SoaSE 1.12 via Impulse, or download GalaxyForge 1.05 (though I don't know if thats still possible).
Greetings!
