Gameex unhandled exception after running demo game

[helpman]

So here I am with my weird problems...

My system was ok running windows 7, but all of a sudden I find myself with windows 10 installed.... calm down, everything seems to run fine... but the sound. There was no sound at all.
I solved it installing an old windows vista driver version for my on board sound card.

Now, Gameex... takes some time to load, but works any way... until the screensaver kicks in.

It happened twice (and I'm loading it again so I can copy the error details).

After I click any button to exit the screensaver, the picture on the screen freezes, then an error window pops up.

Unhandled exception. And a button asking to continue anyway. There's no other choice than continue, then I can see the gameex menu, but as if it were a sticker. Nothing works. Only way to exit it is by task manager and force close gameex.

Dialog title: GameEx|Demo:|Punch-Out!! (Rev A)|60/60| (the rom name is the one used on the screensaver)
Text: Unhandled exception in an application component. If you click on continue, the application will bypass this error and will try to continue.
Error in the application. 
Options below: Details / Continue

On the details mentions some directx thingies... I'll try to reinstall directx just in case...

oh nice... now after updating the video card drivers windows looks ok, but running gameex the picture goes crazy, just as if gameex would be changing resolution. doublechecked and on the setup wizard gameex shouldn't change the resolution

 

EDITED: accessed through teamviewer and it looks like all gameex configuration is gone, and it's changing resolution, my theme dissapeared... weeeeird

 

EDITED 2: I can see my theme and everything, but it looks like I have it unregistered. doubleclicked to make sure the registration file is added to the windows registry, everything seems to be fine... yet I can only choose arcade84c as theme (even though I have many others installed), my custom text is missing, and it keeps loading on 800x600 or something like that

 

EDITED 3: All emulator options and settings are lost too

Sounds like something got botched during the upgrade.

I would try reinstalling gameex over the top of itself, and seeing if that gets things back to running normally.

Also, it is usually helpful to see your ini and logs.

I've found an old thread about configs files missing, so I went to the config folder of gameex and renamed the backups of ini files of the latest update... it worked!

... but after restarting windows everything was broken again...

so, considering how slow windows 10 runs on my arcade, and that you can revert it back to your old OS... windows 7 here I go again  wish me luck
