It reads around 2000 and sometime more clips and then fails.
happening on call to FPTag.BlobReadPartial
It is in C# ,.NET enviroment.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

What Randall describes would normally result in an exception relating to authentication failure.
The problem being described sounds more like something that happened with earlier versions of the .NET wrapper and was due to a mismatch in calling convention signatures to the underlying C SDK. This was initially fixed by patching the IL, but since later versions of the framework allowed this type of change by addting attributes then this was incorporated.
I would suggest downloading the latest version from SourceForge (posted in November 2009) and trying that out.

We happened to have these errors when things between 32 bit and 64 bit stuff got mixed up.
