Enabled built in ad blocker results Slimjet unable to start

[smyl3210]

Hello,
I enabled the built in ad blocker, then slimjet disappeared or crashed (crash/reopen dialog displayed to reopen but it didn't work). After that I couldn't start again slimjet. Nothing happens when I try to start it. I already killed all slimjet processes, but the same. Updated to the newest version, but still doesn't work...

Something is wrong with adblocker files. I renamed the folder "Slimjet\User Data\Default\adblocker" to something else, and slimjet is able to start again.
My original folder contains 3 files: English Sites (required).txt (size: 1.5MB), UserBlockList_flag.dat (size: 0), UserBlockList_rule.txt (size: 0)
