Hi i just reached lvl 14 in hl2 the "our benefactors" stage. I just can't jump now... i thought it was coz of the new gravity gun... but it seems it's a bug in the game. The only suggestions i found on the net were to load from an earlier point. My last save is in lvl 12 and i really don't want to go through all of that again. So does ne1 have a fix for this... or do I have to play lvl 12 and 13 all over again?
