UB Data Migration Pro install: Permission denied

Thank you, I did that for both the var and pub folders.  Now ran fine.

Now when clicking the UB Data Migration Pro button in the Admin section it says:
Whoops, our bad…
The page you requested was not found, and we have a fine guess why.
If you typed the URL directly, please make sure the spelling is correct.
If you clicked on a link to get here, the link is outdated.
 
Thoughts?

I just downloaded the latest version from the site yesterday. UB Data Migration Pro v2.0.4
I made some permission changes on my own and am now to this point:
CException
Application runtime path “/var/www/html/magento2/pub/ub-tool/protected/runtime” is not valid. Please make sure it is a directory writable by the Web server process.
/var/www/html/magento2/pub/ub-tool/yii/base/CApplication.php(293)

281             return $this->_runtimePath;
282         }
283     }
284 
285     /**
286      * Sets the directory that stores runtime files.
287      * @param string $path the directory that stores runtime files.
288      * @throws CException if the directory does not exist or is not writable
289      */
290     public function setRuntimePath($path)
291     {
292         if(($runtimePath=realpath($path))===false || !is_dir($runtimePath) || !is_writable($runtimePath))
293             throw new CException(Yii::t('yii','Application runtime path "{path}" is not valid. Please make sure it is a directory writable by the Web server process.',
294                 array('{path}'=>$path)));
295         $this->_runtimePath=$runtimePath;
296     }
297 
298     /**
299      * Returns the root directory that holds all third-party extensions.
300      * @return string the directory that contains all extensions. Defaults to the 'extensions' directory under 'protected'.
301      */
302     public function getExtensionPath()
303     {
304         return Yii::getPathOfAlias('ext');
305     }

I’ve run through the recommended permissions on the Magento install guide numerous times.
 
I ran the chmod -R 777 /var/www/html/magento2/pub/ub-tool/protected/runtime command and now I’m back to the page cannot be found issue I had earlier.
Thank you Mall so much for helping me through this process.
Thoughts?

I did check app/code/Ubertheme/Ubdatamigration/Block/Index.php as stated above, and since I’m running the latest version pro 2.0.4 the code change had already been made.
Any other sugestions as to why the tool is throwing a 404 error?
I purchased this tool last night since I was on a deadline to get this server transfered and have yet to be able to attempt to use it.
 
Thanks in advance.

I fixed the nginx problem, it was missing a fastcgi_read_timeout in the ub-tools section of the website config.
 
Now I’m getting this:
CException
