XS++ v4.1 problem

Hi! I have a SE w200i and I want to unlock it, but the problem is that it is DB2010 CID53. I try with XS++ 4.1 in Linux but when I enter in GDFS tab and I selected "Read Lock" from Phone-Lock has appeared next error "Loader file (data/loader/db2010_cid00_prodid_p3l.bin) does not exists!
Phone rejected the loader!"

What can I do? Why appears this error?

Maybe SonyEricsson Have new CID53 Security much Stronger then before

The phone is since 2008....what can be the problem?

maybe software not support your phone..:a004

I think so.
