To make Rebed work in win7, you have to change the permissons for each of the dats, for example-> to edit the capital ships in rebed -Go to your rebellion directory and open GDATA -Find the CAPSHPSD.dat and open the properties -Open the securities tab and click on the edit button -In the first box you select your user -In the permissons section check the box for full control -Apply these settings and quit out. Rebed should now work for the capital ships, obviously you have to do this for every .dat you want to modify which should be displayed in that french error message
