Workspace size reverting back to 64000

[Iron74]

I have an issue on Cognos Planning - Analyst whereby I update my workspace size from 64000 to 512000 but every time I log back in it has reverted back to 64000, meaning I'm unable to access several cubes.

Is there a way of overcoming this?  I've never encountered an issue with changing the workspace size before.

Sounds like a Windows permission issue - make sure you have enough rights to update the filesys.ini file
