No problems going from alpha3 to alpha5, it reuses the same database.

But if the database is not already there.. it is unable to build a new one:

  allocating_buffer_pool.cpp:  49:sizeof(BufferEntry) = 32

  allocating_buffer_pool.cpp:  50:sizeof(BlockEntry) = 16

  player.cpp        : 569:empeg-car 3.00-alpha5 2003/12/24.

! tags.cpp          :  61:Failed to open tags (0xc0041002).

! memory_stream.cpp :  42:MemoryStream failed to allocate memory.

! tunedb_disk.cpp   : 878:Failed to build database. Bad. 0xc007000e

! fidfile_disk.cpp  :1167:Why did write return zero for offset=0, size=0?

! fidfile_disk.cpp  :1167:Why did write return zero for offset=0, size=0?

So, for now, use upgrader to install v3alpha3, rebuild the database, then use upgrader again to install v3alpha5. Then play with it!
