so I realised there was a big a detail i had missed in my other post about this, so here goes...
Once i downloaded fallout 3 from steam and started playonmac install, I came to the screen that says
" Do not click next until Playonmac is finsihed installing Fallout 3" or something like that. What I didn't notice awas a small error window that came up, titled "Wine Tray system error (i think that's what it said)
and no text beneathe, only a picture of the steam icon
(grey valve thing)
I'm pretty sure it was soemthing about the game.
anyway main problem is that playonamc is not installing the steam version of the game.
Any help would be awsome!
