Something wrong?

I have installed the new beta version of 1.01.048. I started to scan the hard disc drives but it flips by for one second and stopped. Nothing on the list and error report was generated:

Recuva v48

===========

System Info: MS Windows XP SP2

[14:7:48] ErrorNo: 8 OtherInfo:cundelete_ntfssearch3 Error No:536870920 ErrorInfo:Failed to reserve memory.

[14:7:55] ErrorNo: 8 OtherInfo:cundelete_ntfssearch3 Error No:536870920 ErrorInfo:Failed to reserve memory.

I have accidentally deleted some of our files and I need to restore them.

Any advice please. Thank you. :(
