Problem when adding ssis packages from microsoft visual source safe 6.0

I have created a integration services project on machine A and have added to visual source safe 6.0

When i try to take the project from source safe and store that on a different machine B i have a problem with it....

I check in everything on Machine A

When i try to add on machine B it tries to add it with "Name of package(1)" which means that its adding a copy.But it dosent do for all only for few

Could anyone let me know what the problem is?

Any time you see an unexpected "Name of package(1)" package added to you project, means the folder where the packages are stored already have a file with that name. Depending in how you do it, a file that is not part of the project may still exists in the folder. Use a windows explore to check what I am saying.
