I finally got to download from the host using IE. Sort of. But I didn't get my file at all. Instead I was prompted to download their download manager, which, wouldn't you know it, had adware and crap hidden in it. I declined all their offers, and my anti malware blocked them from hijacking my browsers with AOL installations. And even after bypassing all of that, I still could not download my file, because it said it had "problems with the connection".
I think from now on I'll be avoiding this host indefinitely. Truly a shame...
Edit: And unclicking that terms and conditions box only gives me an error like before downloading. :/
