Not able to start a new JIRA Instance using different credentials

[bipin23]

Hi All 

I am new to the JIRA Software and I  have installed one free 30 days JIRA Software Trial. My free license got expired and I don't have any administration rights to perform any operation.I did uninstall and re-installed the JIRA again but my new installation is taking the same old user credentials.If i use my old user credentials it's showing me the same message of expiry (which is common)

How do I install a new JIRA Software with new credentials for admin ? 

Your help will be really appreciated!!!

Hello,

If you trial expired, you still should be able to provide a new license. Do you mean that you can not login as an Administrator to Jira?
