When I unfroze mine, the CAA were completely happy with a countersignature from my Fleet Manager, certifying that all the hours flown with that airline were correct. The requirement to have all P1/us time countersigned disappeared about 3 years ago. The information is contained in a GID, I forget which number. You shouldn't have a problem.
Congrats on thawing it out!!!!!!!!!
