Can't find devices

[arimak]

NextPVR can't find any device(s), tho it worked perfectly before... a day before it normally recorded, next day it couldn't find devices, I didn't install any new software, hardware, no restart of the pc..

So it's throwing exception when I go to Settings -> Devices:
"Unhandled exception has occured in a component in your application..."

Under Details is this:

just-in-time (JIT) debugging instead of this dialog box.

My Device "Evolve Venus", it's an AF90xx chip device, is working ok, is visible in Windows' Device Manager, and it works in other apps (DVB Dream). Btw I tested it on another pc with Win 8.0 Pro and NextPVR - there it is working ok.
My OS is Windows 8.1 Pro, so it could be maybe some combo of Win8.1 & NextPVR & last week's windows updates? Don't know... :/

I tried freshly reinstall NextPVR (with deleted folders in c:\Users\Public\... c:\Program Files\... deleted things in registry too),
reinstall drivers, tho it wasn't problem of device itself...
All without positive effect..

Thanks in advance...

Hello arimak. The same issue was reported August 3, also involving Windows 8.1: http://forums.nextpvr.com/showthread.php...exception&

Unfortunately that user didn't post back to say whether or not sub's suggestion solved the problem, but perhaps you will?

[Reddwarf]

At least, you should post logs.....

[arimak]

sure, Logs...

[sub]

Maybe just try installing http://www.microsoft.com/en-nz/download/...x?id=30679

[arimak]

I did try it already. "Visual C++ Redistributable for Visual Studio 2012" and "Visual C++ Redistributable for Visual Studio 2013" too

Last updates of Win8.1 were on Thursday 11th September, a few days on Saturday was my last recording (all ok)..
Next day on Sunday nextPVR couldn't find the device..

[sub]

To be honest - I'm not really sure what to suggest. I'm running on Win 8.1 here.

[Zeb]

Is it even possible that an error this serious could be related to SlimDX?

No, I'm pretty sure it wont be related to this. It's missing something that Unmanaged.dll depends on. It doesn't depend on SlimDX. That's further up the stack.

A recent thread by pcostanza looks very similar: http://forums.nextpvr.com/showthread.php...t-then-Bam!
Have you tried reinstalling the driver since reinstalling the Visual Studio?
