I have installed the standard SolidWorks blocks for electrical and hydraulic schematics.  When I drag them in from the file explorer or the design library into the drawing I get the following error:

"The default templates are not valid. The problems can be resolved by correcting the default templates under the options dialog.  Do you want to continue with a blank template?"

I have created my own drawing templates that are stored on the server and directed the options for "file locations" and "default templates" to this location.

If I continue with the blank template and select the "custom sheet size" option the block appears as it should.  If I select the "standard sheet size" and the correct template for the size of drawing I am using all I get is the 1st angle image block that is contained within that template sheet.

Can any one point me in the right direction to stop this dialog box apperaring every time I insert a block?
