application crash

[85justine]

I have a problem with some application. It works in this way, that from the first computer are sent some files to the ftp(using application - navori serveron the first computer ) which is on the second computer and later they are downloaded from ftp on the third computer using my application (navori player)which later wshould display these files.
and here are problems. There is no problem with sending files from first computer to the ftp but with downloaded this files on the third computer. There is a problem with file about 20mb, there isn;t with small files.
I have download speed 4Mb and upload about 300kb.
them here too, problems arise especially with larger files, eg about 20mb (the link is 4mb and sends about 300kb).

In the event log appear error:
timestamp
0x4aad0aa8, faulting module mshtml.dll, version 7.0.6001.18000, stamp
0x4791a74c time, exception code 0xc0000005, fault offset 0x00113c9f,
process id 0x324, application start time 0x01ca5932a572bc1a


I am using Vista Business
When I used total commander on the third computer the wasn;t problem with downloaded this same file.
What can it be wrong?
