I had a problem just after first launching JDownloader and starting a download when it had to reopen it kept trying to reconnect to megaupload and failing so i had to delete the data and start over
im suspecting that it may happen again when i have to close JD part way through the download because im at a public library and they have limited open hours (at home im on dialup) The file is 3.55gb so i would appreciate any help to prevent the connection issues

also on another note how do you reassemble a file that is split into 9 parts to upload to a server?
(yes my download is split into 8 410mb pieces and 1 358mb piece)

thanks
