Cant access my vault

I upgraded from v1.0 to v2.0 a few days ago and have been having no problems untill today when i was unable to access my vault i last put files into it first thing this morning then the next time i tried to access it i get the error below

Any ideas of whats going wrong I need to access the vault as it contains my college coursework that needs to be submitted very soon

you should ahve 2 files related to secure access. “SecureAccessv2_win”.exe and “SanDiskSecureAccess Vault” the .exe is the application and the Vault file is the actual encrypted database where all the files are. Did you accidently delete the Vault file?
