Cannot install QLink after wrong user+password.

[lirano]

Hello,
I have installed QLink (QLink_3_01_0156.exe) with wrong user+password.
Uninstall + install I got a message of invalid Username or PSW.
I cannot install again, because I am not ask to enter user+password.

I deleted all the registry related to QLink and ESignal, but in vain - I cannot enter new user+password.

Need some help, please
Thanks.
