After examining the SVN repository of Wordrider, I found the variable in the file UserProp.java.
Well, here is the guide for those who need it:
Make sure FRD is not running
Locate file c:\Users\[username]\AppData\roaming\VitySoft\Frd\frd.xml and open it in a text editor
Add the line
Language: XML
<entry key="firstSleepTime" value="[number of seconds you wish to wait before each download]"/>
(for example this adds a 2 minute timeout):
Language: XML
<entry key="firstSleepTime" value="120"/>
Save and close the xml file, start FRD
Enjoy.
