Selenium IDE: [error] Timed out after 30000ms

I'm currently testing a website and my first command (i.e. 'open') is always thrown with "[error] Timed out after 30000ms". I added 'waitforPageToLoad' with target=100000 but the same error is consistently thrown which results to "Test case failed". Which command should I appropriately use to prevent this error? And can I specify somewhere in the tool that minimum page load toad time for any of my test case is 60000ms?

Please advise. Thank you
