I'm not wishing to be all doom and gloom but there's a good chance it's fecked the scope if all's tight and you've checked the usual stuff.
Hawke make some nice clear optics for the price but they're not the most strongly built scopes and springers can break them from time to time and the Fenman, like most other Theoben springers, has a well earned reputation as a scope wrecker due to their unusually sharp snappy recoil.
You really need a proper spring rated scope on your Fenman, mate, or it'll only break the next Hawke.
