Exception when opening connection to .mdb file

[Lorenzo Vita]

When I try to open connection to a .mdb file ,
the UCanAccess driver throws the following exception:

This happened with UCanAccess 2.0.7.
Can you help me?
Thanks in advance.

It looks like a format issue that causes some problem while Jackcess is reading a table.
Could you attach your mdb (obviously if there aren't private data)?
