Issue Description:
After installing a Community Pack, when booting, Nerf ArenaBlast crashes with an error complaining about a missing file.
Solution #1 - Fixing UAC locks on Nerf files and folders:
If you are experiencing this error, you are likely running Windows Vista or newer (although it might happen on Windows XP in rare cases). If this is the case, the cause of this problem is likely hidden User Account Control settings preventing files from being installed properly.
First, find and open your Nerf directory, usually located in C:\Program Files\Atari\Nerf. Now, open the System folder inside. Organize these files by type and browse to the group of .ini files. If you cannot see hidden file extensions, visually, the icon for an .ini file looks like a notepad with a gear on it. Take note of your User.ini and Nerf.ini files. Does either file have a small, golden lock over the icon? If not, skip to the next paragraph. If so, right click on either file and select Properties. In the General tab, make sure the check box for Attributes: Read-only is unchecked. Next, in the Security tab, click the button labelled Edit... In the box that opens, search through the Group or user names: box for a name in this format: Users (<YOUR COMPUTER NAME HERE>\Users). If you do not see this name, you will need to create it. Do so by clicking the button labelled Add... In the large text field at the bottom of this new window, type in "Users" without the quotes and click the button labelled Check Names. If done correctly, the input you put in the text field should change to match the aforementioned name format of <YOUR COMPUTER NAME HERE>\Users with an underline. Click
OK.
Select this user group in the top selection box labelled Group or user names:. Next, make sure that in the bottom box labelled Permissions for Users, the check box for Full control in the Allow column is checked. Click OK then click OK again. Repeat these steps for the other .ini file and lastly, for the Nerf folder itself.
At this point, you will need to re-install the Community Pack and run the updater again. It is smart to apply these steps to any Nerf ArenaBlast installation before installing the CP, if you can remember to do so.
Solution #2 - Fix corrupt or missing files:
While unlikely, it is possible that either by using NerfEd or simply by dragging out, deleting or renaming Nerf files to receive this same error if the file was needed for booting the game. This only occurs if you've played the game before receiving this error, or used NerfEd and accidentally saved over a critical engine file. If you suspect that you have irreversibly damaged a critical system file, your first step should be to take a screenshot of the error window and post it in the forums so an administrator or fellow player can identify the broken file and send you a new copy of said file. If it was simply a matter or renaming or removing a file, check to make sure you don't still have the file before posting, as this can save you some headaches. Renaming the file back to the original name and/or replacing it in the correct folder can fix the error if this is the case.
