click the little arrow, then open the folder it's in. (If it's not there anymore you can go to tools -> show downloads) If it doesn't work then, it's a corrupt download or something not to do with Chrome.
I've tried all that. It works if I access the file with any method OTHER than chrome. Also, any method using chrome that used to work no longer does.
Any suggestions? Do I need to reinstall chrome?
Thanks
Edit: problem randomly disappeared. Thanks anyways
