I've had this problem ages ago. When I first really got serious into map making i discovered the proedit map protector and I asked for help at Sovereign modding empire (Clokr_ still remember my quadruple post there?). Anywayz, i couldn't use proedit then and nobody was able to help me there so i put off the protector for a while and used starforge. But a recent problem came up, i used starforge to protect my map and it doesn't compress sounds so it added 6 - 7 mbs onto my map. Now my last resort and hope is Proedit.
This is the problem i have:
I put the mpqctrl.dll thing in the same folder as proedit. I run it and everything goes fine. Until i hit open and selected my map (.Scx)(which is unprotected). Then suddenly this msg popped up that says "this map is protected by - Unknown" which i know i hadn't protected the map and i can still open the map. When i closed the pop up window i can't use any of the proedit options except "open" and "map colours" which seemed like i haven't opened a map at all yet. Can someone help me? Thank you!
