In order to freely use all the advantages of the VKontakte social network - to freely exchange information and view files of all formats - often there is a need to eliminate some malfunctions. For example, a situation often occurs when the video "In Contact" does not work - it does not load beyond the first frame, the sound is played late and so on. What is the cause of all such problems?
The fact that the Vkontakte video does not work could be influenced by a large number of factors. However, the most common ones are not so difficult to detect. Many of the causes of malfunctions can be eliminated in a few minutes without the help of specialists.
The simplest thing that can be done to restore the ability to play videos is to try downloading them in another program for viewing web pages. If there are no problems there, this means that the video in the contact is not working due to the mismatch of the plugins. Thus, you can simply update or reinstall the familiar browser.
The second fairly common cause of problems with video playback is the obsolescence of the Flash player. To check whether this reason is relevant in this case, you need to right-click on the movie window and select the item about the program Adobe Flash Player in the drop-down list. The table that appears may indicate that the version of this utility does not match the browser. Then, to watch the video "In Contact", you need to download the latest version of the Flash player on the official website and install it on your computer.
The cause of many problems and the slow operation of applications on the Internet can be an overloaded cache. So, if the video "In Contact" does not work, you need to find in the browser settings menu the item related to deleting the contents of the cache.
Of course, the roots of the problem with video playback may lie deeper. Today it is not so easy to avoid malware infection of the operating system by actively using the Internet. Virus files can be downloaded without the knowledge of the user, subsequently affecting the operation of many programs. Malicious software develops rather quickly and can not always be noticed by antivirus software. So, if the video "In Contact" does not work, then it will be useful to manually scan the system and find out if it contains files that carry a threat.

Situations when it is impossible to play a video can also arise due to the features of the social network itself. For example, the video file format is simply not supported by the site player. Watching the video may not be available optionally due to any problems, it may be that access to it is closed by the privacy settings. In this case, if the corresponding message appears on the screen, then you should not make this an occasion for excitement. You can try to find the same video on the page of another user using the search bar.
These are just the most common situations that you may encounter when watching a VKontakte video. But at the same time, the causes of all malfunctions are most often limited to this list.
