Try this:
1. - Create a new folder in the same folder you installed XoloX and name it 'temp'. (i.e.: /program files/XoloX/temp).
- To create a new folder within a Windows directory; Right Click > Choose 'New' > 'New Folder' and rename it to 'Temp'.
2. - Now within XoloX go to Tools > Preferences > Downloads Tab. Set the 'save incomplete files to this directory' setting to the new folder you just created.
