It worked once, the other time didn't. The second time, admittedly, the filesize was around 80MBs, whereas the first time it was just about 30. Perhaps filesize has to do.
More than the redirect tho, the program freezed after it finished uploading, so that I had to manually close it. By freeze I mean that it didn't unlock the options and it was still as if it was uploading, though it did upload it all and the file was correctly uploaded on the org since I confirmed and checked the upload.
