Error during opening a sav file

[Manos Markakis]

Hello
I try to open a sav file after i worked with it for 3 hours and when i open it, 
the database that i had is lost and a message saying error C:/......  near 
offset 0x28f0: invalid variable name '???????' .  What can i do? How can i open 
the file and most important will i be able to see my database or its gone and i 
need to do it all over?

Thank you
