Error Index was out of range and Attempted to divide by zero.

Dear all,
I am setting a CVA experiment in the SSI Web 8.3.10 version.
SSI Web suggested that I should generate the minimum 37 tasks but because I believe that it will be difficult for the respondents to answer all of them, I generated only 10 tasks. SSI Web gave me a warning but generated the taks. Then, I checked the questionnaire for possible errors and it was correct.
I saved my survey and then I tryied to upload it on the server.
I got a warning that the CVA file is empty and I need to generate tasks
But when I try to generate the absolute minimum of the task suggested by the software and I get this error message.
" Attempted to divide by zero"
When I close the survey and try to access the CVA experiment I get this error message
The index was out of range. It must not be negative . parameter name: index

Can anyone help me with this?

Many thanks
