You may try another way: instead, make a SQL backup from the source server.
You will get a .bak file.
Then, restore to the new server, using the generated .bak file.
Finally, check that the connections to the new server match those of the old one.
Here's a link that you may use for these operations, if you are not familiar with them:
Back Up and Restore of SQL Server Databases
This would be much more safe than trying to import from a 145 Mb file :)
Good luck, hope this helps.
