Urgent- Tier 2 General Application Sponsorship License Number not found

Dear all,

I am currently encountering an issue during my Tier 2 General Visa Application online. It appears that when I attempt to input the Sponsorship License Number, the system warns that the SLN can not be found. I have double-checked with my employer the License number is correct.

As my current visa is due to expire in a few days I am really trying to get this application out ASAP. If anyone here had a similar experience before could you share how this issue might be resolved?

Thanks in advance
