I'm downloading a large file on the basic version of Limewire. I have a modem connection, unsure the size of it, but pretty fast! The file has gone 87% of 1,870 MB and has just hit a brick wall. I have another one that is 17% of 1,974 MB and hit the brick wall at the same time. Just last week I was downloading a similar file and the speed was 120 KB/s. What could have changed?
