We have an application that is using the Profile SDK to access data in T1/T2/T3 files. Everything was working perfectly until a month ago, after we upgraded to Profile 2011. As we have not yet carried over the information (from 2010 to 2011), our application still needs to retrieve information from 2010 files.

Since the upgrade we keep getting this error:
System.Runtime.InteropServices.COMException (0x8000FFFF): Cannot read this file version: \\server\data\T1 - 2010\Doe, John (111222333).10T
at profile.IProfileFile.LoadFile(String AFileName, Boolean AReadOnly)
at ProfileConnect.ProfileInfo.GetClientT1(String vsFile)

Upon running the following code:
Dim oFile As profile.T2010T1File = Nothing
oFile = CreateObject("profile.T2010T1File")
oFile.LoadFile(vsFile, True)
...

We get a similar behavior with the following code:
Dim oFile As profile.T2011T2File = Nothing
oFile = CreateObject("profile.T2011T2File")
oFile.LoadFile(vsFile, True)
...
where vsFile = \\server\data\T2\Company Inc (20101231).GT2

And with:
Dim oFile As profile.T2010T3File = Nothing
oFile = CreateObject("profile.T2010T3File")
oFile.LoadFile(vsFile, True)
...
where vsFile = \\server\data\T3\Trust Me (20110531).10R

Anyone has any idea how to resolve this situation?

Looks like one of the computers had not been upgraded. Making sure every workstation was running the same version of Profile fixed it.

what sort of data are you extracting?
