May be a goofy question but ...

Is it okay to repair the cracked game via Origin or No Way Jose?

My Sims can't cook or use the computer and the game has begun crashing when saving or exiting.  It was working fine (have everything, including Spa Day/Kitchen Stuff, for it, from you guys) but last week and this week it has started to give me escalating problems.  I tried the fix, deleting the cache folders, etc., even replaced everything with a back-up copy after which it worked for a little while then got corrupted again, so any thoughts?

Thanks!
