If you do not have SQLCE installed, you will get this error:

Gasmate.exe
MissingMethodException
File or assembly name
’system.data.sqlserverce,
version=3.5.0.0 culture=neutral,
publickeytoken=3be235df1c8da2d3′,
or one of its dependencies, was not
found.

The solution to this is to install the SQLCE cabs I have hosted or download it from Microsoft.

If you have an old version of GasMate, you might get an error similar to this:

GasMate.exe
SqlCeException

The solution to this is to either delete the database, or export your data and modify it to re-import it.

If you have a smartphone(WM Standard), you will get this error:

NotSupportedException

Microsoft.AGL.Common.MISC.HandleAR(PAL_ERROR.ar)

System.Windows.Forms.Control._InitInstance(WNT wnt, UInt32 dwStyle)

Unfortunately at this time, WM Standard does not support some of the form elements I am using in GasMate. Later on there is the possibility of a fork that will work on WM Standard.
