Hello Tara,
Could you please be more specific?
Where have you 'uploaded' your map to?
What kind of data is in your map?
How big is your dataset?
How far into the ArcPad application are you able to get before the crash?
What is the last thing that happened before the crash?
Were there any error messages?
What kind of tablet are you using?
I want to help get to the bottom of this - but will need more information to narrow it down.
Thanks,
Hannah
