well, tried installing again, and it turns out this error appears once the 3.3 is installed, i got in game with the 3.2 release. the fsopen ver is 5.2 (i got the standalone version of the mod)
You still didn't answer the important question, and by your post it seems that you don't understand WHAT I'm actually asking. 5.2 is the build number of the Launcher, not of FSO. You see, for 3.3(+3.3a patch) we added support for setting the initial positions of multi-part turrets, to something other than straight up or straight down, thanks to the newer animation code. If you're still using the same build that was included with 3.2, then that's the problem right there. The animation code isn't supported by those older builds. To facilitate this change, more recent builds were included with the 3.3a patch. Included are the 3.6.7 official builds, which were released in early september (IIRC), the 2005/12/22 build, which was the last one to support the older (3.3 default) animation code, and 2006/01/09, which is the most recent build that lacks any serious bugs for TBP, but it requires the new animation code. A readme included with the 3.3a patch RAR file, has instructions on how to use it.
If you don't know what build you're using, open the launcher and take a look at the location bar just next to the "browse" button at the top. Click in the location bar and scroll right with your keyboard arrows. Then post which filename of fs2_open is listed there.
