We have no issues with chrome (that I know of) I use it myself, could it be some chrome extension you have installed? Do you get any errors with chrome on the site or does it simply not log you in. I'd like to find out why it's happening so it does not happen to other people. Thanks for letting me know.

As for old downloads, you should be able to find them here

If you're having any issues finding them let me know what your missing, I'll sort it out for you.
