Hexxit RAM problem

[MrNeroy]

Hey guys. I've got a problem (which seems to be RAM-caused) when I try to play Hexxit. 

After installing the Technic Launcher and Hexxit, everything works fine for once. But when I try to play it again, I always get the 'shutting down internal server' error and minecraft keeps teling me it has run out of RAM.. I tried to allocate different 'sizes' of RAM to it (1GB, 2.5GB, 3GB, 4GB and even 6GB), but nothing seems to work... The only fix I found is to delete the .technic folder and reinstall everything, which is getting pretty annoying after a while...

Also - sorry if this wouldn't really belong into this section, but I thought, now, that I already had a poblem to post, then why shouldn't I  try to post another one with it - I can't seem to play any other Modpacks than Hexxit (at least not Blightfall or Tekkit) because I get the same error when I try to play it, even for the first time...
