I am having the same exact issue. No new plugins were added, we just updated to WP 3.4.1 and we now have a redirect loop issue.
this is the text we would get:
The webpage at http://www.paylinedata.com/login has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.
I did find a workaround that seems to work for now. If you go into the settings of the plugin under the “General” section of the settings there is a series of text fields with Login, Register, Forgot Password and Profile with a text field next to each. I put in user/login, user/register.. etc. and this seemed to work and no more redirect error. It would be great if the developer would issue a fix though!
