1.  Try to get it working and copy all the information somewhere else first - the following might destroy it!
OR 1.  Try to get it working and put the information on a new pendrive and throw the old one away.
2. Find an electronics or model enthusiast with a soldering iron.  Persuade them to try to, VERY CAREFULLY, with a heat shunt (eg. a pair of pliers crimped onto the connections to remove excess heat), re-solder the connections.
3.  Be aware that there is no guarantee that, if it shorts out when you plug it in, it might cost you a USB port, so don't plug it straight into a laptop (less replaceable) without trying it out on another computer first.
