Thanks for the warning, I didn't realise, I'm sorry.

Are my corrections right?

I got the launcher to work but now it has stopped working while I was trying creating a Sim.
Luckily for me my sister has a Sims 3 disc so I used hers which installed properly and I patched but then when I was creating the Sim it just stopped, I could move the mouse but nothing responded. I guess this could just be one of those problems but I'm planning to get WA tomorrow so hopefully it'll be sorted out tomorrow or in the near future but if I still have problems I'll come back here to this post.
thanks for the help.

EDIT: grammar, capital letters and punctuation has been change as advised below.

I just reinstalled the Sims 3 because I needed to get back a file I deleted and now when I try to open the launcher it says "a problem has occurred" and "windows is searching for a solution to the problem", can anybody offer any help, I only reinstalled so I could get the new patch.  

Thanks for any possible help  

EDIT: corrected capital letters and any grammar mistakes as advised below.

I've just tried to patch my game but it won't let me, it tells me the update is ready and starts to download but then it'll finish before it tells me there is an invalid file error, anyone else having this problem?
