Login button freezes

I have a question. whenever i try to log in to maple from this computer (its very old, started around v60. and my other computer works fine) i enter my ID and password, and click log in. but then, the log in button turns gray (unclickable) and stays like that. i once left it open for about 2 hours, still stuck. i tried reinstalling and it didnt help. anyone knows a solution?

Seems like your computer and the login server aren't communicating properly. As for a specific solution, I have no idea.

Whenever this happened to me, I would just reboot MS.
