Opening Bundle Files

Sometimes I get this when it takes a long time for the wave forms to draw so if you haven't already try cleaning out your pic cache folder. Also do have anti virus on your machine? If so turn it off. If I leave mine on it causes any projects with samples to load painfully slow at first.
 
 

I'm not clear on your Issue. 
You say both bundle ,CWB and Normal, CWP  stall n opening on the new computer? 
 
Do you still have your old computer and everything is fine? 
 
I transfer between computers a lot and have never had a problem. I don't use bundle I always store everything as a Normal or CWP file. 
I use folders for each project and in that folder is the audio file etc. Per project folders is what you need. 
 
You then just copy , drag drop, the folders to an external drive where you leave them as back ups, then copy, rag drop those to the new machine. If your running the same versions of Sonar, same plug ins and vsts installed,  on both machines there should not be an issue. If there is then something is not right with your new computer install of Sonar. 
 
If you still have the old computer then "save as" all your projects as CWP files into folders and check the Copy Audio with project box.

That's exactly what I do also. The problem may be the vsts you mentioned. The old PC has a few vsts that are not on the new PC and I have added about 100 to the new pc that are not on the old.
 
I'll check the projects on the old PC for plug-ins and remove them before I save the files and try to open in the new PC.

Normally that shouldn't stop a CWB or CWP from opening.  You'd just get the warning that "ancientVST is not installed" or something similar.  Then it would open without the old VST.
 
My suspicion is that a CWB taking an hour and still not opening would imply a corrupted file.  This is a big reason most of us now use CWPs with Per-Project-Folders.  But don't take my word for it, keep trying.
 
If they still open on the old PC, open the CWB and save it as a CWP with Per Project Folders.  Then transfer the CWP folders to the new PC.  That should avoid the 'corrupted file' worry.
 

I think I've solved my problem. Really dumb reason. I had to change the permissions of the files for the users on the new PC. I've only tried two of the files but they both opened in a matter of seconds and neither would open at all before.
 
Thanks for all the replies.
