Uploading a Video

Hello, my name is Andre. I'm new to Smart FTP Client, but I really do like it a lot. I have transcoded a video into FLASH and it is now an .FLV file. Every time I try to upload it, it has a "timeout" error. I dont seem to know what to do, can you please help me.

I've tried PASSIVE/ACTIVE modes, I've tried "Keep Alive" feature.

Please help me with uploading this FLV file. By the way, it's 320 MB.

Thanks a lot and God Bless,
