Problem to upload files

[Tadzio_G]

 Hello everybody. I was wondering if anyone could help me to solve a problem:
I have just installed Coppermine gallery and intend to use it for making available both videos and pictures. The problem at the moment is that I can't upload certain videos, I don't know why. The limit for video files is currently set for 30 M, and I can't upload a simples 1.5 M Windows Media type of file. The thing is that I began the uploading process ok, but after it is finnished I get the message  " 0 files upladed sucessfuly", and when I check to make sure of the file, sure nough it isn't uploaded.
Anyone?
  Thanks a lot.

T.

Give some more details.
Put on the debug mode and post the error/warning messages you receive while uploading.

do not upload the video files using http uploads, but use ftp-upload and batch-add (the gallery admin always should use this method, only "regular users" should use http uploads).
