Bug Style CSS

Hello. I activated the pro version of the theme and I have a big CSS problem. I do not know why but my page is totally disorganized. I delete and reinstall the theme without success. I show you a screen of the page (I handed the free version for worries of presentation with respect to my client). What can I do to fix this problem EMERGENCY? Thank you in advance for your help.
