Did u get to the event viewer? If so was there an entry relating to FSX? If so open the entry.
Its not a faulty mobile its a faulty module that will be highlighted - that will be causing your CTD (Crash To Desktop). It will likely be some form of .dll module if you can identify that then post here we maybe able to help.
No need for an uninstall of FSX just yet!!
