While I wouldn't recommend having such a huge list of simultaneous downloads, here's how to proceed to get the back dlding:
In FrostWire, click the Library tab and then select the Incomplete folder.
In there, look for the files you were downloading, select them and then click the resume button.
Simple enough.
