step 5 problem

when I try to load blocks pb, db, ob, fb on the step 5 program. The pb and db load fine. ob 1 loads fine but the other ob and fb blocks will not transfer.

When I try loading the program

WHEN I TRY TO LOAD SCPCHPPX.INI I GEAT A MESSAGE THAT THE SAYS

ProgFile=F:\ELECEN~1\S5PLCP~1\SCRAPC~1\SCPCHPST.S5D
Drive not ready
The default value will be entered:
ProgFile=C:\STEP\S5_DATEN\NONAMEST.S5D

I can not figure out how to change the location

There is no f drive

It's a long time since I did S5 but create a new project, then point to the location of the blocks i.e. within s5 set-up set the paths to the files you require like .s5d & seq etc. then save the (ini) file, what the problem is that someone has created the project where they have an F drive, when you load the project file (ini) it tries to search for the locations on "F", so providing you have the .s5d & .seq files then creating a new project & pointing to these files you should be ok.
