OK, here we have 2 links, the 1st one is not on FileSonic anymore, the 2nd one is. What the FRD is doing - it tells you that both files are OK, when you check them using FRD. BUT the real thing is, the 1st one is not there - you can check it by FileSonic link checker. So, the things are not working right over here and it's probably because FileSonic pretends the file is still online in regular browser...
Yes, I know. The point is that the FileSonic's link checker gives correct results - so the queston is if it's worth including it in verification process. But you are right, it's FileSonic's fault.
