Import button not working

In the log is an indicator for the problem visible:
An exception occurs:

java.nio.file.InvalidPathException: Illegal character [?] in path at index 2: \\?\D:\Research\EPA_Project\Lake_Erie_HAB\Data\remote_sensing_data\MERIS_RR\BDP_meris-ds_MER_RR__2P_000010\EN1_MDSI_MER_RR__2P_20110503T154936_20110503T163329_047971_0112_20190129T100542_0100\ENV_ME_2_RRG____20110503T154936_20110503T163329_________________2632_102_112______DSI_R_NT____.SEN3

Strange! Where is this illegal character coming from?

There were similar but different reports before:

Java error when open product

OK, thank you for the clarification. One of the new features of SNAP 7 is Virtual File Systems support, and it seems you have an old product path stored which is no longer compatible with the current version. If deleting C:\Users\[your_username]\AppData\Roaming\SNAP doesn’t solve the problem, try to re-install SNAP by choosing to delete all SNAP previous data when uninstalling.

@oana_hogoiu Maybe you have an idea what’s going wrong?
