Yes. Your problem is: You use a very old version 6.2 pro that does not support shaders and had a lot of bugs. If you got it from a friend then this might be an old beta version that is not officially supported.

So I recommend to buy a stable version or upgrade for free to the latest one (if you have a license and a download password).

If you only want to check this software then better get the free evaluation version from the website.
