Install Problem on Step 3 of 4

I have downloaded the Zend trial and am attempting to install. I specify the root info as http://domainname.net/amember as well as the DB info which matches the created MySql DB. The problem occurs when I attempt to move beyond step 3. It hangs for about 5 seconds and then redirects me to http://domainname.net/?step=5 which just shows the homepage. The DB tables are not created and I find myself right where I started.

Any help is greatly appreciated as I would like to be able to test this software out.

Thanks

Jeff

Still no progress on this one. Does anyone have any experience with this problem?
