[Plugin: Register Plus Redux export users] Can't download the export file

First of all, a BIG thank you to the author for this plugin!

However, i came across a little bug: When i export the data, it says something like file saved in “/tmp/plugin_registerplusredux_eu_exported_users-20110326-001004.csv”
but when i click the Download Export File button nothing happens ??

Any help would be greatly appreciated.

Cheers,
Ciprian
