Problems with watershed modeling in HEC- GeoHMS

[BhuwaniPaudel]

I did watershed modeling in Hec-GeoHms and try to import in HecHms but it shows error and unable to import. Could you please suggest what was the reason. My GIS is 10.3, HecGoeHms 10.3 and HecHms 4.2. It show proj file is 3.5 version req to convert in 4.2

I have modified the title, moved its content to the body of the question and added a few tags... please inspect to ensure all is still good

Thank you Dan, question is more clear now.  By the way, I am your former student. I am modeling a watershed for rainfall runoff analysis. All good but I am unable to import basin file or open project file which was developed in Hec-GeoHMS to Hec-HMS, 

Thank you

Grief!!!!!  Fall 2003... a long time ago... hope all goes well.

As for your problem, that is a bit out of the standard realm, I will flag https://community.esri.com/groups/arc-h?sr=search&searchId=a72d1b69-49f4-4457-90c0-0a57c74f19cb&sear... in the hopes someone in a similar area, is more familiar with what you are doing.  My email can be found on my profile... send a note some time.‌
