without any specifics, about start-up settings/the actual current turn/initial generated map/usage of custom ship designs/modded files/etc..., it is very hard to make any statement about whether there is a problem with the AI level and/or compare it to the game play results of another player.
What i normally do is make a save in the first turn before i do anything, and make (and keep) a save at regular intervals (or when something weird happens). This can help in tracking down any problems. If you have got a first turn save and your current save then post links to those here. With those someone (SD or a forum member) can take a look at the problem, by loading the saves, or even try to replay them.
Since everything is stored in the save file, you do not have to upload any modded files/ship designs.
