So I must to buy new version? True?
IF you want the new features! If you don't buy it, you can STILL install the new GSX installer, and they are some improvements to GSX too (new Voices, for example), just you won't see the new features (SODE jetways and animated passengers )
about my second problem? Two jetways?
Your screenshot is too small. You said you see 6 jetways, I only see two. One of them doesn't look like a GSX SODE jetway so, clearly, it won't move with GSX.
I cannot possibly know if that other jetways is animated or static but, if it's animated, it will continue to work as before, with CTRL+J, and it it's static, no program in the world will make it move. You MUST replace it with a GSX jetway, then it can move.
Of course, all of this will ONLY work after you buy the Level 2 expansion, unless you are on a Trial airport, or an FSDT airport.
