Hi Nathan,<br><br>OK - by counting the number of occurances of '<maplayer' in the project file, I count 50 layers. Sounds a lot but there were no problems in 1.6 with this number!<br><br>Sorry to be stupid, not sure what you mean by load the file by itself. Are you saying that there is a way of selectively loading layers on opening a QGIS project file? Or do you mean opening the file in a text editor or something. If the latter, then it certainly loads the XML OK and there's no evidence that the file is corrupted.<br>

Very many thanks for the quick response! OK, running from the command line gives me slight more info, to be sure:<br>

Additionally, when I start QGIS this way I get a pop up window within the graphical interface that says:<br>
<br>
The layer /mnt/bunker/ross/Research/PhD/NewMapMarch2011/VectorBackgroundMapMarch2011 is not a valid layer and can not be added to the map<br>
<br>
The strange thing is that I'm pretty certain there is no problem with the project file. It's timestamp reads 22 April, when I last worked on it. I.e. the version of QGIS has changed but my file has remained constant.<br>
<br>
Many thanks!<br>

Hi Ross,<br>
<br>
That sounds a bit strange. Can you start QGIS from the terminal and see what the output is when it locks up.<br>

Hi there,<br>
<br>
I've updated my Ubuntu 10.10 installation to use QGIS 1.7. I put a lot of work into a project using QGIS 1.6 but it won't open in 1.7. The layers all appear but then the screen freezes as though QGIS is rendering the resulting map forever.<br>
<br>
A bit of googling revealed that there was a bug at some point which required the placement of 'gdal' between all <provider></provider> tags in the project XML file in a scenario like this. However, I tried this and it didn't work. I also have read various posts that say the use of 'on the fly' project appeared to cause problems going between 1.6 and 1.7. The project in question does indeed use on the fly projection.<br>
<br>
As a final note, I have an ECW raster layer in this map that requires the modified GDAL to work. I thought that the crash might be to do with the upgrade having removed my modified version of GDAL. I therefore recompiled it all and have checked to see that my version of 1.7 can now read ECW files and it can (when they are presented a a fresh layer and not as part of the problematic project).<br>
<br>
This is a really, really important project to me and I do need to get it back if at all possible. Please can anyone help?<br>
<br>
Very many thanks!<br>
Ross Purves<br>
