Good time of the day!
First of all the software is great! 
For our needs we created a script which converts txt documents to pdf (using command line) and it worked great until we put it into the MS task scheduler and mark “Run whether user is logged on or not”. From that time on pdf creator stopped working. There is no any failure messages appear. Can we comment that issue or suggest a way how to get away of the problem?
Thanks in advance. Victor, Russia!
