Unhandled Exception - unable to run or start

[allknowing2012]

I am stuck - unable to start my xlights now.

Here is what I think made this happen: I was going to look at imported show - so I pointed show directory to \downloads .. it went and try and backup a bunch of files in that directory - errored on a file. Unable to backup hadoop blah blah blah file.

I couldnt get the imported file to load so I reverted back to my usb e:\shows directory. That is where it dies now.

I downloaded a fresh copy and placed in a new directory .. same problem.

I ejected my usb and it starts fine.

Reinsert usb and it gives me errors on failed to copy the file (see attachment). Not that it is trying to copy to E:\\  << two slashes? is that the problem?
Anyways .. you can see it fails with the error 3 -- then exits out of xlights.

Sort of stuck here... The usb is fine.

I copied things out .. cleared some directories .. ran it with my backup and then it finally started working again.

No issue at this point unless you want me to triage anything to help handle this "exception" reported.
