This last weekend I reformatted my desktop and only installed v. 4. The initial download of resources was like 3.9GB. I just went into to read Wallace's grammar, and it's not there. So I thought "hey, it must not be prepared for v.4, maybe I need v. 3 and then v. 4 will show it." (by the way, Wallace does come up in v. 4 on my laptop).
Anyway, I just installed version 3, put in the license and all the books and can read Wallace in v.3, but still not in v.4. How long do I need to wait? Is this an issue with installing v. 4 first?
