Fatal error with Report

Anyone experience the following problem?

I Create a report - add field into the report
Have quite a lot of field to create so the best way is to copy and paste.
Selected the created field then use copy and paste to create multiple fields
Compile and get fatal error message.
Next get a whether to report or not message and when select to report, I get report installer not found.
The whole program just shut down.

Emailed support center but have not gotten any reply. I was wondering if I’m the only one.

Thanks in advance.
