Unable to access data on Cruzer Pop

I am using a Cruzer Pop SDCZ53. Since last 2 days i am unable to access my data files stored in flash drive. data is stored based but a .lnk file is shown with the name of flash drive which is not accessible. An error massage which pops us describes that file with name “~$WNEK.USBDrv” Please please please revert with the remedy. i am stuck due to unavailability of data.

I suspect the drive letter of the flash drive has changed and the links are to the old drive letter.
