WinInet.dll file get erase at the end of transfer

[CortexWayne]

Hello,

I have built an ftp transfert with the wininet.dll wich works on 99% of my clients except this guy wich at the end of the download receive the error:

12002 from Err.LastDllError wich seems to be "The request has timed out."

Others receive
Internet Call Back Status :40
INTERNET_STATUS_RECEIVING_RESPONSE
Internet Call Back Status :41
INTERNET_STATUS_RESPONSE_RECEIVED
Internet Call Back Status :70
INTERNET_STATUS_HANDLE_CLOSING

but he never get the last 41 call back of the last packet. This guy is in another country so it's impossible for me to get to his computer exept remotely. After 2 days I ask him to buy a new internet modem, he did so but it didn't change anything. Maybe he only changed his router...

Sorry for my poor english...

Any Idea or suggestion is welcome.

Martin
