BF 1942 probs

[hos]

1st, before someone jumps down my throat, I HAVE USED THE SEARCH, but Im still confused. I own '42 and RtR legally. I want to use a no-CD crack to speed up load times. I used the crack just like it says (replace the 3 mod.dlls and the .exe). I also tried the "renderer.allowAllRefreshRates 1". When I try to join legal servers (not cracked) it crashes to desktop in the wrong resolution. Undo everything I just did, and it works fine again. Will these cracks work for legal servers? Tweak Town's article said it would.
