16 bit app getting killed with metaframe 1.8

[phildude]

We've got a custom app that a client has been using for years with success (16 bit vb app), they applied a service pack update to Citrix (2 I believe) a couple of months ago, and now, when our app launches, it dies most times before it even makes it to the login screen. Other times the login screen will appear, and then it will die after a second or two. Any thoughts, or any ideas how to troubleshoot or track down the error message? I'm not a Citrix expert by any stretch.
Thanks,
Phil

What is the error message?

This doesn't look (on the surface) like a Citrix issue. Can the app be run via a Terminal Server client, or does the same thing happen?

Does this happen when the Citrix Administrator attempts to use the app?

I hope this helps
