Blank texts when opening the game

Hi! Lately i had this problem with my game and no idea why (i didn't touch anything, but tried to install island paradise). 

I tried reinstalling everything but it's still the same. with mods or no mods, nothing changes. i don't know what to do

Welcome to the Forum @Moon!

Try downloading the "1.67 superpatch" for The Sims 3. You can either google for it, or also download it from step #2 in this tutorial here:
https://www.games4theworld.club/t1171-must-read-how-to-install-the-sims-3-correctly

After you managed to download it, simply double-click on the file and WAIT. At some point you will get a message that the patch has been applied successfully, or something like that.

You're not done though. You'll then need to download the "Ultimate Fix" from steps #4 and #5 of the above guide. You'll get a .rar file. Extract the folder named #Crack. Copy the TS3W.exe and TSLHost.dll from inside. Paste the two files under

C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin. Replace the existing files when prompted.

And ... if you did everything correctly the game should now work fine. Good luck!
