I have a big problem with lauching QGIS. I have been using QGIS in the past, but now I can't launch it. I tried re-install, but it doesn't help. I tried install different versions of QGIS (1.7, 1.8, 2), but in every version process is finished after loading plugins and python...
When I want to launch QGIS via command line... QGIS is open, and after loading plugins/python nothing happens... Windows is closed, processed is finished.
In install post reports there aren't any errors.
Do you have any idea why?
