i mapped a level and yesterday the perspective-screen was black (= cant see 3D-View of my map). But i can open the map in NS2 and "play" it (its only 1 almost playable techpoint).
Is there a chance to solve this somehow ? (i mapped 1 techpoint in 7-8 days and i dont want to redo this. otherwise i would quit mapping for NS2 when i know this could happen again after days of mapping)
