Dear community,  
I am trying to save an array and afterwords load it into the program again on the same machine. For that I use JLD2 (v0.1.2) and Julia 1.0.3. This works for several array types and sizes but it fails for an 100000x101 Array{Array{Float64, 2}, 2}. I successfully save it with the standard method “save(path, title, data)” (the file has a size of 1.1GB). But if I try to load it again with “load(path)”, the message

```julia
Error encountered while loading "..PATH...". 
Fatal error: JLD2.UnsupportedVersionException()

```

appears.  
Does anybody have an idea what the problem could be and how to solve it?  
Greetings,
