overflow error

Hi, 

I can not login the filevista application anymore. 

The following error message is shown. 

Arithmetic operation resulted in an overflow.
Error 105 (Provider v. 4.0.14.1): Cannot read header of: Event
Error 250 (Provider v. 4.0.14.1): Cannot create row: Table: 'Event', RowId = 20446

What is the cause of such problem? and how to solve it. 

I have restart the IIS web service, the problem is persist. 

Thanks,
trevor 

Hi,
It seems your database file is corrupted. Please send us App_Data\database\FileVista.vdb4 file and we will try to fix it.
I guess you are still using v4.1, if you also send App_Data\FileVista.config file, we will send you a prepared installation for the latest version 4.5.10.
