After further investigation...I was able to pull up this error.
Microsoft JScript runtime
error '800a139e'
ASP Uploader needs read/write permission to the system temp folder. If your host doesn't allow such access, you can specify a different path using TempDirectory property. at function Ox34
/aspuploader/aspuploader/resources/coreimpl.js, line 1
I own the server and I enabled read/write permissions on the temp directory and it still doesn't work. Not sure why this message is coming up since everything was working and no settings have been changed.
