Conflicts and corrupted worlds

Hello guys, i'm struggling with a lot of stuff and i can't figure out what i'm doing wrong. I'll try to be as clear as possible to resolve this. First, my configuration is i7 2.4 8GB RAM windows 7 x64 (the game works like a charm). I have installed the base game and every expansion including university life. i have last update (obviously 1.50) and last content patch (v2 i guess, definitely the last one that the launcher shows). I am trying to install every single world (or neighbourhood), buildings and every store items (from your media account) from the very first to the last one (installed them as sims3pack). so i copy everything in the download folder, install them through the launcher (found this is the fastest way), i have successful at every single one. Then i use Delphy's Dashboard to check my files and apparently all the worlds are corrupt, and a lot of conflicts generated by the files that are installed by the worlds and also the store items. Do you have any idea what's the culprit and how can i solve that? I found out that when i enter the game the worlds don't show up (i still have to pay simpoints for them). I'm lost, i have no idea why is this happening....

Hello,

Those "gold" items have to be turned off, it's the in-game store.
Go into the in-game Settings and look in the third or fourth tab, it has an option called "Enable Store Mode". Turn that option off.
Do the other worlds show up now?

Ok. i decided to do a fresh install of the game, with your help Admin, maybe you could make it easier for me. What i intend to do: install the base game, all the expansions, all the updates and most important all the worlds, buildings and store items (plus store fixes). i will install the game from your tutorial then what do i have to do? so after your tutorial i will have the base game, all expansions and all updates. now what are the steps and in which order in order to reach my goal. what do i need to install first, do i need to delete the files in backup and cache, can i open the game in the meanwhile. things like that. i look a lot on you forum but can't seem to find any explanations on how to do it. if i'm wrong please give me some links to the topics. thank you very much

Hello,

Sorry for the late reply!
Unfortunately we were not able to get back to you in time. I'd like to apologize for that.

Do you still need assistance?
