options in AdminCP not working

I'm trying to install 2.6.3 for VB 3.6.8 and am getting the following error:

Warning: FUNC::require(./arcade/lang/lang_Arcade_en.php) [function.FUNC-require]: failed to open stream: Permission denied in /arcade/functions/functions.php on line 576

Fatal error: FUNC::require() [function.require]: Failed opening required './arcade/lang/lang_Arcade_en.php' (include_path='.:/usr/local/php5/lib/php:/usr/local/lib/php') in /home/.accelerationdryer/michmomsquad/michmomsquad.com/forums/arcade/functions/functions.php on line 576

I'm not sure what to do from here. I had a similar error earlier, except it was line 37 or something, and it turned out the entire functions folder was corrupt, so I removed it and uploaded it and all subfolders again, and now am getting this error. Am I still having problems with corrupt folders, possibly? I've removed and uploaded everything again to no avail.

Oh, and maybe I should add that the error happens when I click any of the links in the Arcade section of the admincp.

Can anybody offer me some support on this?

Can someone please help me with this? I still have not figured out what went wrong.

re-upload and overwrite all files ...

I have done that twice. I've removed them all, and re-downloaded the package from the site and uploaded again and everything and it's still happening.

Okay, I am in the process of uploading and overwriting everything again, and I'm getting these error messages as I try to upload:

I am using the latest version of Firefox's FireFTP -- could the problem be the FTP program?

Since I can't seem to get rid of the folders that "don't exist" I tried renaming it. It did allow me to do that, so I am in the process of uploading it all again. Let's hope it works this time.

FIXED. Finally. Thanks for your help.
