Unable to connect to soundcloud

I just downloaded the current version of Cross DJ (free) in order to check out how this software works. I have been unable to connect to soundcloud - I get an error message that says this:
"The webpage cannot be displayed
Most likely cause:
•Some content or files on this webpage require a program that you don't have installed.
What you can try:
Search online for a program you can use to view this web content.
Retype the address.
Go back to the previous page. "
Please let me know how to fix this issue or if I have to download something in addition. Also, why does it default to IE? Can it default to Chrome instead? Thank you!!
