Hi and welcome to the forum.

There are many experienced users of the program here who can help with any issues you have or 'how to' questions..

See this topic in case of technical difficulties for what is required before posting.

Providing some detailed information is essential, as we cannot see what is happening on your computer screen.

Should you wish to post examples of your creations, there is a separate Media section of the forum specifically for this - the link is at the top of the page
