Its seems to me that ALOT of ppl thinks when you get a minidump and the box appears and you click the ok butten it sends automatically, but its actually not. It should open your mail box and say something like
Please attach 'C:\Users\Multianna\AppData\Roaming\Ironclad Games\Sins of a Solar Empire\MiniDump\Sins of a Solar Empire.exe[vb4.2][09.24][17.30].dmp' to this email. You can also help by running Start->Run->dxdiag.exe and attaching the results of clicking "Save All Information" to this email. With your help you will never see this dialog in the final game! Thanks!
This i think has to be adressed somehow as IC is missing alot of minidumps
