Hi. No, I'm not using any plug-ins. I also checked the plugin folder too, nothing is in there. This error started right after I installed the update to 9.2 yesterday (not sure if that's related).

OK ill tag @Jason Carr here and see if it makes any sense to him.

[Niko78]

Thank you for your time. Very much appreciated.

@Niko78 This does look to be an error related to the new update and the startup screens, though I'm not sure exactly what's happening. You can try turning off startup screens under Tools > Options > Game Startup to see if that fixes the error for the time being. Also, if you'd be willing to zip up and PM me your LaunchBox\Data folder that would help for me to identify the error.

Mr. Carr: Data zip sent. I genuinely appreciate your time. I will try turning off the the Startup Screens and report.

I checked the Startup Screen option and it was already unchecked/disabled. There is no ability to turn it on either. I haven't upgraded to BigBox yet, if that matters.

I see; okay. I'm testing with your data and I haven't been able to replicate the error yet. Does it happen with every game? What specific games is it happening on?

Hello, again.

It doesn't seem to be related to any game.. yesterday I was playing King's Quest, and when I close the game the message was just there. Then, again yesterday, I was sitting watching TV and I had LaunchBox open in front of me and the message just popped up at random. Today I was playing Medieval II: Total War and when I closed the game the message was there. The games still work and the import tools too, I believe. I just get this error message (possibly) at random.

Ah, I see. Okay, that makes more sense. I'll see what I can figure out.

[Jason Carr]

Alright, I think I have this figured out. I'll put out a beta here soon with the fix.

Awesome.

I just spent the last hour testing my build. I received the error message; ignored it. I then proceeded to test every single system/emulator, and they all work. I updated the Meta Data with no issue. I also installed a new DOS game and download the pictures for it, tested the game; no problems.

[Niko78]

For the last couple days I've had zero problems; now I have another pop-up window reporting an error. Not sure if it's the same error (likely).

Yeah, the error is likely to be completely random. I have it fixed already, but I haven't put out the beta that fixes it yet.

Thank you, Jason.

I'm a patient man, no worries. But out of curiosity, and forgive my ignorance, but how is the fix/beta applied?

You will need to go into Launchbox >tools>options and in the updates section make sure you check the tick box for Betas. I would also recommend to not have the tick box for download in background checked. It will apply the beta update over your existing set-up. It will not make any changes to your data and imports. If the next beta fixes your issue and you no longer want to text betas just uncheck that box.
