Issues happen in The Sims 3 Seasons.[SOLVED]

Regarding the latest expansion, The Sims 3 Seasons released, I have a couple of issues here. I've succeeded to install this expansion, the problem itself is in-game:
everytime I plan for outfits and hit "everyday" tab it crashes, though I run gamebooster while playing the game and I think my system requirements is just fine playing it. Second problem is now I'm having error message... I can't save the game just like what Lady Eldi had discussed it on this threat https://games4theworld.forumotion.com/t4523-the-sims-3-save-errors-fix-error-code-12-13-15-16 . I've tried almost all of fix recommendations but, those don't work it out yet. I've deleted inventories that can make saved memory getting large to prevent it, but still doesn't work. And when I tried to move my family via porter it just crashes. Oh I forgot to mention, this save error message 12 occurred to me just after my sim married other sim, and automatically the other sim moved in, but for other time I tried to save, it just worked. And other time I saved it, as in today, it's unable to save. oh help me. I'd really appreciate it ...

yep, it's error 12. Some say, cutting the saves folders and move it somewhere, make the folder empty, can make it works again. But I haven't tried it. And yes, I checked my save games have large files. It seemed like, slight memory size from the previous save game and current which I wanted to save really affected this error to occur.

//EDIT

ah I think I have solved this problem. Just tips, what I did was just minimised it then I moved (even if I deleted it, it won't affect too much since the game would recreate this package as I saved it) travelDB.package on this root C:\Users\Documents\Electronic Arts\The Sims 3\Saves and opened the file I wanted the game saved. I went back to the game and just saved it. The Error 12 code gone, I could save it again.
