Your file attached fine. Thanks.
The rebase function works for me as expected. Perhaps you're having a problem because the range is so large. Try this: Zoom out as far as possible. Go to strategic view. Now select the rebase icon. You should see a large flashing area that represents the rebase range. Left-click any city within the range. The fighter should fly to that base. You also can see this in normal view: Go back to the save file. Again, zoom out to the maximum. Now recenter the map so that Frankfurt is at the far left of the screen. Yekaterinburg should be on the far right (unless your maximum zoom level is different than mine). Again select the rebase icon. You should see a blue line near Yekaterinburg that represents the boundary of the rebase range. If you don't see any of this (in either view), please post your DxDiag file (see my sig) so we can see your graphics information.
