VBA Not Loading Every time

We have an issue since upgrading to GP2013 (1745) where the VBA will not load Everytime.

The GP Client is located on machine where the users access through an RDS App.

Even when logged onto the machine directly, the VBA may not load every time.

We setup a new remote machine and the same issue occurs.

The VBA project in Excel is available, so we figured the issue is on the Dynamics GP side.

Has anyone experienced this sort of issue, or any recommendations.

Thanks,

Mick
