Connection History from server end

HI,

I really hope you can help. I am in an investigation at work. Someone exported data and the manmagement think I helped.The person in question asked me to do a TeamViewer session but that session never took place. I have checked the connections file on my laptop and the last date I did connect was at least a month before the date in question. The thing is, the connection file is just a notepad document, which is easily editable. They wont know about the connections file but when I tell them about it, they will see taht you can edit it yourself....Is there any way I could get an official extract from the back end to support what I am saying -who can I approach about it..... been using the free version.....thanks.
