Limited edition Sims3 plus pets question

I have the limited edition store bought Sims 3 plus Pets. I was able to get HELS and the store updates to work but can't seem to get any of the expantions to work. I've tried the fixes and it just keeps crashing. Do I need to get rid of my store copies?

their separate disks. with my pets installed I don't get the "insert disk" problem but without it I do. I don't have anything mounted. would I still need to mount one of the downloads even if I have the pets disk in the comp?

Hello,

No need to mount anything and no need to keep any discs inserted.
Which fixes did you apply?

Woot I got it working. Thank you. I downloaded a newer fix from that link and used that this time.

I had to just do a recovery on my comp cause it had so many errors. I think that was part of my problem along with me not knowing what I'm doing .

I didn't instal world adventures this time cause it told me the region didn't match. Will I be able to add it later? If I follow the directions that are in the instalation folder for that download will it mess up the other downloads?
