DCS Loader Critical Error Question "Date/Time"?

I'm not sure whether 5  volt sound files are still available on the MTH web site.

What sound file are you using??

Hi Greg, yes, they are still available. If you try to use a PS3 or a PS2 3V file, the loader app will catch it and generate an error code stating it's incompatible.  The file I'm using is "pr_e8_ic_010214_final.mth". Another thing to add is that I can't upload the same sound file I downloaded from the engine. In other words, it won't take back what it has given me ( I have the same issue in real life! LOL).

I got this very same issue the other day trying to relaod a centercab file to  PRR 2500 HP Centercab.

Matt, I've searched around the net and here for this issue and I saw one post from back in 2012 in which I believe the member may have posted the same question but I didn't see any response or remedy. Surely this isn't a checksum or something trying to sync up with the computer date? 

I had better things to do so I put that one back on the to do shelf.

Should I move this to the Technical forum?

It's fixed. I had uninstalled and reinstalled the loader app numerous times without success. Last night I uninstalled the loader app again and afterwards I went into the Windows Registry (regedit.exe), performed a search and removed all line items with MTH. Reinstalled the app again and now it's working. I've successfully written to the engine a couple of times. Just for notes, I had removed the DCS Loader app using the control panel in windows as well as using the .msi extension in the program to repair/remove. I don't know why the app quit working to begin with, however, it doesn't appear all files are removed when you perform an uninstall command.

Try CCleaner after you uninstall things, it cleans up a lot of registry entries that get left behind and sometimes cause issues.  The free version is all you need for what you're describing.

Thanks for the recommendation, I'll give it a try.
