Are you using wifi when trying to place your order? If so, that's happened to me a few times, just turn off wifi and download using 3g. Should work fine. I'm using the YouTube android player API to play some youtube videos. My code is working fine on: Samsung S3 Samsung Galaxy Tab III Nexus 7 (with Android 5.1.1) But it doesn't work on the Nexus.

Ok so yesterday I downloaded the latest version of NMM because it's been a while. I installed it but now every single time I launch it and load up a game, it says that something went wrong and it creates a trace log. I would post this trace log on the forums for NMM but apparently you need to pay to gain membership in those forums and I simply cannot do that. So I'm asking anyone out there, can you please read this trace log and see what's going on and what I can do to fix this?

Delete the user config file

You can try this if your nexus mod manager won’t start. The config file associated with the game profile might have been corrupted, and you might have to set up a new config file.

It happens when you have downloaded a mod for a new game, and that runs in conflict with your previous games. You can delete the config file associated with the Nexus Mod Manager client.

Don’t worry about doing this won’t delete your save game data. Browse to the following folder on your system:

C:/Users/Your name/AppData/Local/Black_Tree_Gaming/NexuxClient.exe…../version number(0,63.13.0)/user.config

It won’t affect your existing games or mod profiles; you will just have to get the start menu again for all the games individually.

  • Then delete all contents of the Black Tree Gaming folder. Then re-launch Nexus Mod Manager. It should open and start looking up for games installed on your PC. If another error pops up on the screen about exceptions, just hit “continue” and it should keep working.

Check your antivirus for issues

Often the culprit why Nexus Mod Manager Won’t Open could be your antivirus software which might probably be blocking some of the critical files required for the execution of Nexus Mod Manager to work.

You can do this by temporarily disabling your anti-virus system or add NMM to the whitelist or adding the program exe into the exceptions list.

Downgrade your Nexus Mod Manager

If you have installed a new update, it might be the reason why the nexus mod manager not opening. It usually occurs when a new update file wasn’t installed correctly, or it is not compatible with the system. To fix this, try to revert to an older version of Nexus Mod Manager. You can get the old files form here.

  • Go to Run.
  • Type “regedit”.
  • Go to edit>find and type NMM.
  • Delete all the files associated with NMM.
  • Reinstall Nexus Mod Manager.
