The problem is:
That is, a missing 'h' at the start of the helper URI (should be "http://..." not "ttp://...").
The default grid info for DreamNation is missing that 'h' (see "Preferences" -> "Grids list", select "DreamNation" in the list, and look at the "Helper URI" line).
I will add the missing 'h' for next release. In the mean time, simply add it yourself in the grids list for DreamNation's helper URI and press "Update selected grid" (this will cause a custom grid info to be added on your system for that grid).
