Installing/Playing Dragon Valley

[djtarty197907]

Hi have purchased this for my daughter, however it will not download states an error as follows:

" The address wasn't understood

Firefox doesn't know how to open this address, because one of the following protocols (sims3) isn't associated with any program or is not allowed in this context.

You might need to install other software to open this address."

is this not a SIMS game? do we need the SIMS 3 game first, what is going on as we have no clue :/

any help would be great!!

thanks
