Connecting to your machine via teamviewer precludes me from helping so in that case 'us' would be anyone else on this forum. The usual approach is that the user with the damaged file would load said damaged file to this forum and some of the more seasoned posters might take a look at it and attempt recovery of the data.

Someone else might be able to connect with you to attempt a remote examination but your best chance is to load the file you have so someone here can examine whether it contains any usable data. Unfortunately these types of requests rarely have happy endings but it can be worthwhile to give it a go.
