Fatal Error on insertion of blocks - WHY?

[CadDraftee]

Hi,

I am trying to insert a block into my drawing but keep getting the following error and then get totally booted out of Autocad all together.

" Exception in Acblock.arx ARX command"

Does anyone know what is causing this and how to fix it?

Must be something is wrong with your computer,
installation or must be a mistake...

Thanks Estassoc, but there is nothing wrong with my computer or installation - it has been working fine for about 12 months now. Just seems to about 4 blocks in particular not the other hundreds that I use each and every day.
