Sims 2 Pets - No-CD problem

[mhead]

Hi,
this is my first post here. I have The Sims 2 with Nightlife and Pets + Family Stuff, H&M Stuff and Teen Stuff.

With original DVD/CDs, everything works fine, but I want to use the game without Pets DVD. I can play the game if H&M and Teen Stuff in not installed, with version 1.6.0.259 fixed exe.

But when I install those Stuff packs, Sims upgrades to version 1.6.0.277 and I couldn't find fixed exe for that version. The game doesn't work with older fixed exe. The game starts normally, but when I try to go to some family, game crashes (some system error).

I tried to use POSEDEN-SIMS2EP4.ISO Maxi-Image mounted with Alcohol 120%, but that didn't work. The game still asks original DVD.

What could I do?
