Hello!
I don't know why, but for some reasons when I select a object in JackHammer (brush or entity) it take for me 4 seconds to select that object...so 4 seconds for every selection. Before I did not have this problem, I selected them in the shortest time...i really don't know what happened, if someone know my problem, please help me!
Thanks! :)

Steam integrity validation fails although everything is in order. Re-acquiring files erases existing configs, options and history.

Are compilers installed correctly, i.e. on the same disk drive as WAD files? JH doesn't export disk drive letter in "wad" field of map file because of compatibility with Valve's tools.

I don't use jackhammer compiler I use compilator 3 which is external to it. It has to work because I had exactly the same before with the free version, nothing changed.
