sort: cannot read: ./mohsen.txt: No such file or directory

[marstay]

Hi, is this error an issue?

I am getting an output like this:
R=0
S=0
The wallet is not vulnerable :11111111111111111111BZbvjr
============END number 8 - Start NEXT ADDRESS ===========
sort: cannot read: ./mohsen.txt: No such file or directory

Also is there any way to speed up the program?

thanks
