Success at last !!!!!!!!!!!
ive been messing around trying various things, i even ended up deleting my permanent install of riverbell, but that made things worse as i couldnt reinstall it
anyway at least that confirmed what we all knew, that theres nothing wrong with the download, but its the download process that is at fault.
for this reason the CD should work as your PC is taking downlaod straight from the disc and putting it on your harddrive, however if your like me, this doesnt work either.
anyway i noticed that even when your installing from the disc, your PC is still accessing the net/bellerock (why ? when your meant to be getting the files from the disc), i found that if you disconnect from the net, thus preventing your PC from connecting to whoever, Voila ! your PC succesfully installs all of the casinos from the disc with trouble.
the exact method i used is
configure your firewall to ask for permissions when your using the disc
disconnect your internet connection
put in the CD and run it
everytime your asked for pemission for connecting to something, click "yes"
choose casino and install it, it should work now!
after the wise wizard has finshed, you should get the "software loading...." bit
at this point you will be asked for permission to connect to the net again.
before clicking yes, you will need to reestablish your internet connection again
after this the casino should load up as normal and you shouldnt have anymore problems, i dont know if this will work for others, but has worked successfully for me today.
