I haven't updated my game to 4.3 (paranoia of EA bugs upon patching), thus I'm still using the released, non-beta AM. However upon loading it said that it will expire tomorrow. Redownloaded AM and it's still the same version.
Do I have to patch the game and use the test version of AM to avoid getting borked tomorrow?
If you're reading these forums, then you should be able to get rid of your paranoia. If a patch is particularly buggy, you'll see plenty of posts here from the regulars who update early, and usually get into testing AM, complaining about the myriad of problem that AM needs to fix. As there are virtually no complaints about major bugs/issues, it stands to reason that it is safe to patch, but look around and find the links to download and patch manually, as with AMB the launcher wouldn't always patch every game properly, and I wouldn't trust EAxis to properly fix it.
The other option, as AM has now been moved from testing to release, you could download and try it. If it really does need the new patch, you'll get the "core mismatch error" when staring the game. I believe your paranoia about patching in this instance is misplaced.
Spent some time yesterday looking through various forums to check for any problems with the patch; didn't find any. So I updated it today and, as you mentioned, new AM is out, so my fears have been resolved.
Thanks for the suggestions peeps. And yes, considering I'm on holiday, I had plans to play Sims all weekend. Couldn't think of anything else to do apart from, *shudder* going out into the sun.
