Problems with determine corrupted pdf

[maru]

Hello.
My product is GFL SDK v2.82.I write in Delphi.

I have some problems with this PDF file (see attach).
http://www.shareonall.com/P000806191536 ... dd_PDF.htm

When i try to check file format by gflGetFileInformation.
In result i get "Invalid floating point operation".
If I use construction like "try except", file will be blocked, and i can not unlock it.
Please fix this problem or help to unlock this file or maybe some thing else solution.
