Hi, Do you get a out of memory error before this?
If so, then you reached the limit of memory of your system.
... but maybe it can be a different problem.
I suggest that you check the log file of this reload.
You can enable it at document properties -> General Tab -> Generate log file (on the right).
Then, during reload a file with the same name of your qvw will be generate with the extension .log at the same folder as your .qvw.
There you can get more details on the error, you can post it back here so we can take a look and try to understand it.
Hope this helps for now...
Erich
