Client version WoT 9.7 Gnomefather sound mod has a nasty bug with JPE-100. It locked out my game totally when i clicked my JPE-100 in the garage and when there's a JPE-100 in a match. So far it happens only with JPE-100. Reinstall Aslan mod pack latest version (v4.3.3) without GF sound mod solved the problem though. I think you need to temporarily remove GF sound mod from the list.
