Let me know if anything more is needed.

There is nothing that anyone in the community can do to help you based on the information you provide. Whilst you do give the data that Windows is giving you, this information is useless to anyone who does have have your machine in front of them. The address 0023:0043c841 means nothing. Your game has crashed. There should be a Player log that gives more details about what happened.

Thanks a lot guys. Actually i was accessing data from a .mdb file and i had not pasted my mdb file in the test_data folder. Now it works just fine. Thanks a lot guys. :smiley:
