I have tried many files not just one, but it keeps telling that the file is not found. I have tried asking for IT support from my school, and they don't know what to do. I have many projects due this semester, that i have to upload to my website. I was able to upload anytime of files before this 4.4 update. I need to fix this asap, my project is due Sunday at 11:59pm. Please help me at least to temporary fix this so i can turn in my project. My school website only works with cyberduck. I didn't understand the previous ticket you had of someone with this similar problem.
