This looks like a normal 'Cannot open file' message and suggests that the file that cannot be opened is on drive Q: which, presumably. is somewhere on your network.
1. Your workstation does not have a map to drive Q: or, if it does, your Q: drive is not the same as the Q: drive originally referred to.
Solution: Either map you drive Q to the drive referenced OR browse you network for the correct file on the corret drive and use that.
2. There have been some changes to you network and the file is not longer on drive Q:, has been moved somewhere else on drive Q: or drive Q: no longer exists having been renamed or something.
3. Everything is still around but some other change in the network has meant it s no longer available to you. Access permissions and user rights would be the favourite suspect.
For either 2 or 3 you probably need to talk to people in your IT support and find out, in the forst instance, if this is likely. Have they been doing any upgrades or tightening network security recently for example?
If you draw a blank with those we may need to think again.
FWIW can recommend spending a little while to check out Monarch Projects - a very useful feature which can be easily used after about 5 minutes reading.
I hope this helps.
