Analysis:
the issue as per the exception that you copied in the comments says that you Mongodb connection could not be established as there was an issue with Mongodb connection close the previous time. Mongodb will encounter this issue when your computer was forceshutdown due to power outages and other issues.
the exception content from your comments is as below:
[initandlisten] Detected unclean shutdown - /data/db/mongod.lock is not empty. 2015-10-06T09:50:54.164+0100 D - [initandlisten] User Assertion: 98:Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?
Investigation:
Check if there is a file named Mongod.lock got created in your \bin folder.
Solution:
If the size of the file Mongod.lock is greater than 0KB, please delete the file and re run your mongodb. It should work fine. More details at this link
