Catchable fatal error: Argument 8 passed to SRRoomType::getPrice()

Hi,
I've just purchased the $99 bundle, and installed using the 7start quickstart package (and installed the supplied modules and plugins). Going through all the setup instructions, I'm getting the following error when I click on the check availability button, on the pre-installed example module, on the home page.

Catchable fatal error: Argument 8 passed to SRRoomType::getPrice() must be an instance of SRCurrency, null given, called in /home1/mirror53/public_html/guesthouse/administrator/components/com_solidres/models/reservationasset.php on line 289 and defined in /home1/mirror53/public_html/guesthouse/libraries/solidres/roomtype/roomtype.php on line 356

There is sample data already installed, including currency, tariffs for the rooms, room types, asset, etc, so I can't see what the problem could be... any ideas?

Thanks

Solved. Support suggested a reinstallation, and it works now. A couple of issues re: installing 2 modules, but nothing serious I think.
