Cannot Detach a model from a managed model?!

Question

Hi, 
 Ever since i bought the new version of V8i, whenever i try to detach a reference file from a dgn file a message pops up that i cant detach it. 
 I can't find a proper solution to the issue of trying to detach without the window popping up saying I cannot detach. 
 
 I have read all the solution that are available, but none of them worked. I do not have geopak or inroads so i cannot open microstation with geopak/inroads to attempt the other solutions. 
 I'm positive there is another way to get this working without geopak/inroads. This software is pricey enough that I shouldn't run into these problems. 
 i have the 08.11.09.829 version of V8i. 
 i would really appreciate it if anyone could help me figure this out. 
 Thank You!

Someone who did have InRoads/Geopak has worked on those files, and the civil software has written some bit of data into them. Because of that data bit, plain MicroStation is no longer allowed to detach references (at all).
I do not think there IS a way around this, except to open the civil software, detach the reference, and go back to plain MicroStation. I have not found any way to UN-Civil any file that has civil data written to it, either with MicroStation or InRoads. This causes me no end of trouble on certain projects...

As Mary pointed out some form of civil data was written to the attachment elements and the master file. 
 The only way to detach the reference is to detach them within one of the Civil Products.

This seems to happen whenever, at some point, somebody opened the file with a geopak enabled session and then saved it. They don't have to necessarily do anything, as it seems that just by having windows/options open through their normal setup is enough to trigger the locking. At any rate, you'll need somebody with geopak to open the file, and run an mdl (should be preloaded by default) to "purge" the drawing from any smartness (openroads or geopak). 
 
 In the key-in, type/enter: 
 Mdl load Bentley.Civil.Model.Tools.3.1.dll 
 then 
 CIVIL CLEAN 
 then save. Open with regular v8i and you should be able to detach anything. 
 
 My 2c is that it can have something to do with the project explorer settings.
