Recovering data from DumpSave

Hello all,

I slipped and did a terribly long calculation and then used DumpSave 
of a variable defined inside a Module. Previous tests of the code were 
fine, but of course, I was testing outside the Module structure. Now 
Get doesn't load anything, although the data must be on the file 
because it is pretty large (>100 MB). I imagine that DumpSave wrote my 
data along with a temporary variable name in the context that was on 
at that time, as it was one of the variables inside the Module. So, 
now when I try to Get it it loads it up somewhere (takes a little 
time) but then dumps it because the context does not exist anymore...I 
can see in the files that my variable (originally named phase) has 
$anumber attached to it, indicating it is  a temporary variable. I don't
know how to find the context name in the file, let alone how to recreate it.
Any ideas on how to recover the data? The variable is a list 
containing trees (more lists) filled with numbers. Please don't 
suggest computing everything again as it took a week to do it...

Fernando
