ASP.net Access DB Readonly ?? argh !!(Resolved).

[OptimusPrime]

I keep getting the following error when i try to run my asp.net application and can't figure out for the life of me whats going wrong as this only occours on my machine and the code runs perfectly fine on my colleagues ?

I do not have the database open and the database is not set to readonly

Is there a setting within XP that might be causing this problem ?

Any help greatly appreciated
