Hi i have one problem. I using code like this:

Dim pOutputRaster As IRaster
pOutputRaster = pReclass.Reclass(pLandCover, pReclassTable, "ID", "ID", "MANNING", True)
pMapAlgebraOp.BindRaster(pOutputRaster, "Mann")
pOutputRaster = pMapAlgebraOp.Execute("FLOAT([Mann]) / 100.0")
pMapAlgebraOp.UnbindRaster("Mann")

And when i use raster from Folder everything is OK, BUT whe i Use rasters from FGDB - reclass is running fine, and i create pOutputRaster (I see it in my TEMP directory). But when i use pMapAlgebraOP.execute i have error "_message = "ERROR 010316: Unable to open the input raster: C:\USERS\MATTKO\APPDATA\LOCAL\TEMP\ITEMP\G_G402 ERROR 010067: Error in executing grid expression." and my raster is disapear from TEMP directory.
Do anybody know what´s the problem?? thank a lot.
