"Checkout" of a package giving "java.lang.NullPointerException"

Hi,

When I am trying to checkout a package into my Repository Workspace, it is giving the following error: " An internal error occurred during: "Checking out packages".java.lang.NullPointerException".

I tried to checkout the same package using my colleague's laptop and it is working fine and we are using the same HANA studio and client revision 48 (64-bit) and Java version 6 update 37 (64-bit).

Steps I followed:

1. created a new Repository Workspace

2. right-click on the relevant package and click "checkout" -> error

Any feedback is highly appreciated.

Thanks,

Saubhik
