error when loading csv files

help i am getting an error when uploading cvs files from the server and from my harddrive,

from the server i get

no file uploaded

no file found

and from the the harddrive it just seems to stall

any ideas?

i am useing version 3.0.1


never mind,i just cut the csv file down to 400 lines or less and changed the image file extentions to lower case and it seems to clean up the problem
