Help and support

Getting help

In case of problems, always try the CMLCA Companion, the html-based helpfile. Use Help | Manual from the main screen, or press the F1 key from almost any screen.

CMLCA is for free. This implies a number of things:

• There is no helpdesk. Of course you may mail a question, but I don't guarantee you a constructive answer.
• The program is not fail safe. Moreover, I cannot compensate any loss of data caused by programming errors.
• You may contribute to developing CMLCA. In the past several companies have contributed directly or indirectly by funding projects that helped to develop CMLCA. Likewise, several individuals have provided feedback: suggestions, error reports, and so on. You may be the next.

You may also invite me (or one of my colleagues) to provide a training session at your office. Several companies and research centres have done so in the past.

Known issues for Version 5.2

First, remember that CMLCA is highly advanced, and that there is no full test phase before a new release. So, there may some problems with the current "stable" release. Please report problems, so that I may list them here as "known issues", and perhaps provide a solution.
