Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I will need to ask, in order to advise you better, please:
- How did you reinstall Facebook? what process did you follow?
- And was it reinstalled from a backup, or from something else?
- What are the principal things missing in your current Facebook install on your computer?
Did you keep any backup whatever, of the way Facebook used to be installed on your computer?
