Compile error in hidden module

Hi,
I am using my Microsoft Excel to consolidate reports from our field workers, when the error message box appeared and said about compile error.

Compile error in hidden module: This Workbook
I don't remember doing some compile task. What I do with Excel is just simple encoding and making formulas. But I remember, my Excel has a lot of add-ins installed, for my other office mates and field worker will use.
I tried to restart my computer and do the same task again, and same error popped up. I also tried to scan my computer with my Antivirus, and no virus was found.
I ran out of ideas now regarding what is the cause of the error. Please share some thoughts and ideas on my issue.
Thanks!
